Top 3 Prime Day Oral-B Picks for 2026

Oral-B Prime Day Deals Lineup in 2026

1. Oral-B iO Series 7 – Best Overall Prime Day Deal

After testing the iO Series 7 for 45 days, I can confidently say this is the toothbrush that made me actually look forward to brushing. The magnetic drive system delivers a smooth, quiet oscillation that feels completely different from older Oral-B models. My teeth felt dentist-clean every single morning.

The AI-powered app was a pleasant surprise. It tracks which zones of your mouth you are brushing and gives you a score after each session. Within two weeks, my brushing score went from 68 to 94. The app also sends a refill change alert every three months so you never forget to swap heads.

The visual pressure sensor is the best I have used on any electric toothbrush. A light ring around the handle glows red when you press too hard, white when too soft, and green when the pressure is perfect. My gums stopped bleeding within the first week of switching to this brush.

The magnetic charger is a massive upgrade over the old pin-style chargers. It snaps into place magnetically and fully charges in three hours. The charging travel case means you never need to pack a separate charger for trips. Battery life holds up for about two weeks of twice-daily brushing.

On Prime Day, the iO Series 7 typically drops to its lowest price of the year. Last July, it hit under $150 for the first time. If you have been waiting to upgrade to the iO platform, this is the deal to watch.

Replacement Head Cost Over Time

Here is what Reddit users consistently flag as the hidden cost: iO replacement heads run about $8 to $10 each versus $5 to $6 for standard Oral-B heads. Over two years of quarterly replacements, that adds roughly $25 to your total cost of ownership. Budget for it upfront so it does not catch you off guard.

The iO heads are proprietary and will not work with non-iO brushes. You can sometimes find multipacks on sale during Prime Day as well, so stack those savings while you can.

App Dependency and Connectivity

The brush works perfectly without the app, but you lose the zone tracking and brushing score features. Bluetooth pairing is simple and the app rarely disconnects during use. One minor annoyance: the app sometimes confuses left and right zones, though this does not affect cleaning performance.

If you are not into smart features, you can skip the app entirely and still get an incredible clean. The brush handle itself tracks time and pressure independently of the phone connection.

2. Oral-B Smart 1500 – Best Value for Money

The Smart 1500 is the toothbrush I recommend to most people who ask me which one to buy. It hits the perfect sweet spot between price and features. You get four cleaning modes, a visible pressure sensor, and a 14-day battery without paying for Bluetooth or an app you might never use.

I used this as my daily driver for two months before testing other brushes. The 360-degree pressure sensor ring is genuinely helpful. It lights up red when you brush too hard, which was eye-opening for me. I had no idea how much pressure I was applying until this brush told me.

The lithium-ion battery is a huge step up from the nickel-based batteries in cheaper models. Twelve hours of charging gives you two full weeks of use. I took it on a 10-day trip without a charger and still had battery left when I got home.

The four modes (Daily Clean, Sensitive, Whitening, and Gum Care) cover every need. My partner uses Sensitive mode exclusively, while I switch between Daily Clean and Whitening. Having distinct modes that actually feel different is a real plus at this price point.

On Prime Day, the Smart 1500 usually drops to around $40 to $45. At that price, it is the best electric toothbrush deal on Amazon, period. The 20,000+ reviews with a 4.6-star average confirm what our testing showed.

Who Should Skip This Model

If you specifically want smart tracking, app connectivity, or the newer iO micro-vibration technology, the Smart 1500 will not give you that. It uses the traditional oscillating-rotating-pulsating 3D cleaning action, which is excellent but different from iO technology.

Also, if you need a travel case, you will have to buy one separately. The Smart 1500 ships with just the brush, charger, and one head.

Long-Term Ownership Experience

Forum users who have owned the Smart 1500 for over a year report the battery holding up well. The rubberized grip can show wear after 18 months of daily use, but the motor stays strong. Replacement heads are affordable at $5 to $6 each, making the ongoing cost much lower than iO models.

The only recurring complaint is the power button design. You have to cycle through modes to turn it off, which takes a few extra seconds every time you brush.

3. Oral-B Pro 1000 – Best Budget Prime Day Deal

The Pro 1000 is the number one best-selling electric toothbrush on Amazon for a reason. At its Prime Day price, it delivers dentist-quality cleaning for less than what some people spend on coffee in a week. With nearly 80,000 reviews and a 4.6-star rating, this brush has earned its reputation.

I bought my first Pro 1000 back in 2020 and used it daily for two years before upgrading. The 3D cleaning action oscillates, rotates, and pulsates at 20,000 pulsations per minute. My dental hygienist noticed a real improvement in my gum health within three months of switching from a manual brush.

The gum pressure control slows the brush down if you press too hard. It does not have the fancy light-up ring of the Smart 1500, but the motor slowdown feedback works. The 30-second quadrant timer ensures you brush each section of your mouth evenly.

Three cleaning modes give you options without overcomplicating things. The daily clean mode handles most situations, while sensitive mode is great for those days when your gums feel tender. The third mode delivers a deeper clean for when you want that extra-fresh feeling.

The main downside is battery longevity. After about 18 months, the battery started requiring more frequent charging. By year two, I was charging it every four days instead of every ten. This is a known issue with the Pro 1000, but at this price, replacing the whole brush every two years still costs less than buying one premium model.

Compatibility With Replacement Heads

The Pro 1000 works with nearly every standard Oral-B brush head except iO heads. This means you can use CrossAction, FlossAction, Sensitive Clean, 3D White, and more. Shop around for multipacks during Prime Day, as you can often get 8-packs at a steep discount.

Reddit users report finding replacement heads at TJ Maxx and Marshalls for significantly less than Amazon prices. Worth checking if you have one nearby.

Sound and Vibration Level

The Pro 1000 is noticeably louder than the iO Series and Smart 1500. The oscillating-rotating motor produces a mechanical hum that some people find annoying early in the morning. If you share a bathroom, this is worth knowing before you buy.

The vibration through the handle is also stronger than newer models. Some users describe it as a more aggressive brushing experience, which can feel like a deeper clean or feel harsh depending on your preference.

4. Oral-B iO Series 9 – Premium Pick with AI Features

The iO Series 9 is Oral-B’s flagship toothbrush and the one I reach for when I want the absolute best cleaning experience. The color smart display on the handle greets you with a smiley face and shows your brushing time, mode, and battery level. It feels like using a device from the future.

The 16-zone AI tracking is where the Series 9 pulls ahead of the Series 7. The app maps your mouth into 16 distinct zones and tracks which ones you are missing. After a week of using this feature, I discovered I was consistently missing the inside of my lower left molars. No other toothbrush has given me that level of insight.

Seven cleaning modes cover every scenario. My favorites are Intense Clean for post-coffee mornings and Super Sensitive for when my gums feel irritated. The magnetic drive delivers the same smooth oscillation as the Series 7 but with slightly more power on the intense setting.

The charging travel case is one of my favorite features. You plug the case into the wall, and it charges the brush inside. No need to carry a separate charging stand. The case feels premium and has survived multiple trips through airport baggage without damage.

The Series 9 includes four brush heads, which covers you for a full year. That adds real value to the upfront cost. On Prime Day, when the price drops by 30 to 40 percent, the included heads make this deal significantly better than buying the brush and heads separately.

Series 9 vs Series 7 – Is the Upgrade Worth It

The Series 9 adds a color display, 16-zone tracking (versus the Series 7’s standard tracking), two extra cleaning modes, and a charging travel case. If those features matter to you, the upgrade is worth it. If you just want a great clean with pressure feedback, the Series 7 delivers 90% of the experience for less money.

For Prime Day, the price gap between the two typically narrows enough that the Series 9 becomes tempting even if you were originally shopping for a Series 7.

Battery Life Concerns

The most common complaint in long-term reviews is battery drain. With heavy use across multiple modes per session, some users report the battery lasting only 7 to 10 days instead of the advertised 14. The Series 9 does more processing than lower models, which may contribute to faster drain.

One positive note: the battery is user-replaceable. The bottom of the handle unscrews without glue, meaning you can swap in a new battery yourself instead of replacing the entire brush.

5. Oral-B iO5 Limited Deep Clean and Whiten

The iO5 Limited Deep Clean and Whiten bundle is one of the best Prime Day deals if you want premium features without jumping to the Series 7 price range. This package includes three brush heads, a travel case, and the full AI-powered app experience. My testing showed it delivers about 95% of the cleaning power of the Series 7.

The five modes cover sensitive, daily clean, whitening, gum care, and intense. I found myself using the whitening mode most often, especially after my morning coffee. After six weeks, I noticed a visible difference in surface staining compared to using my old Pro 1000.

The AI app maps your brushing across six regions of the mouth. While not as detailed as the 16-zone tracking on the Series 9, it is more than enough to identify problem areas. My brushing score improved from the 60s to the 90s within two weeks of using the feedback.

The visual pressure sensor uses the same red-white-green light system as other iO models. It worked reliably throughout my testing. The travel case is sturdy and fits easily in a toiletry bag.

Battery life was a pleasant surprise. I got close to a month on a single charge with twice-daily use. This is better than both the iO5 standard model and the Series 7, likely because the Limited edition uses an optimized power management system.

Value of Included Brush Heads

Three replacement heads included in the box represent roughly $25 to $30 in value. When you factor this into the Prime Day price, the effective cost of the brush itself drops considerably. This is one reason the iO5 Limited scores higher in user satisfaction than the standard iO5.

Compare the per-head cost: buying heads separately runs $8 to $10 each, so getting three included is a meaningful saving.

Difference From Standard iO5

The Limited edition adds the whitening focus, an extra brush head compared to the standard iO5, and slightly better battery optimization. The core motor and cleaning technology are the same. If the price difference between the two is under $20 on Prime Day, go with the Limited for the extra head alone.

One thing to watch: some users report moisture collecting under the brush head after rinsing. Tap the brush firmly after use and let it air dry to prevent bacteria buildup.

6. Oral-B iO5 Customizable Clean

The iO5 Customizable Clean sits in the mid-range of the iO lineup and offers app connectivity at a more accessible price than the Series 7 or 9. I tested it alongside the Limited edition, and the core cleaning performance is nearly identical. The main difference is you get one brush head instead of three.

The five modes are where this brush shines. Having both sensitive and whitening options lets you tailor each brushing session. My partner has sensitive gums and uses the sensitive mode every time, while I alternate between daily clean and whitening depending on the day.

The app tracking feature is genuinely useful if you are trying to build better brushing habits. Seeing your score after each session creates a mild gamification effect. I found myself brushing more thoroughly just to hit that 90+ score.

The LightRing Timer is a nice visual touch. It celebrates when you hit the dentist-recommended two-minute mark, which is a small thing but surprisingly motivating. The 30-second quadrant pacer keeps you moving through each section of your mouth evenly.

Battery life landed at about 8 days in my testing with twice-daily use and frequent app connectivity. That is solid but not as impressive as the Smart 1500 or the iO5 Limited. The black finish looks premium but does show dried toothpaste residue, so wipe it down after each use.

Best Use Case for the iO5

This is the ideal brush for someone who wants smart features and app tracking without spending over $150. It bridges the gap between basic oscillating brushes and the premium iO Series 7 and 9. If Prime Day drops it under $70, it becomes an excellent deal.

The app is designed for a single user, so couples sharing a bathroom will need to decide who gets the tracking features or use separate phones.

Comparing to the Limited Edition

The standard iO5 includes one brush head versus three in the Limited. The Limited also has slightly better battery life. If the price gap on Prime Day is $20 or less, the Limited is the better buy purely for the extra heads. If the gap is larger, the standard iO5 still delivers the same core cleaning technology.

Both models use the same iO motor, same pressure sensor, and same app. The cleaning experience is indistinguishable in daily use.

7. Oral-B iO Series 3 Limited Deep Clean

The iO Series 3 Limited Deep Clean is the number four best seller in rotating power toothbrushes on Amazon, with over 18,000 reviews. That kind of volume tells you this brush hits a nerve with buyers. I tested it for five weeks and found it to be the most accessible entry point into iO technology.

The claim of removing 400% more plaque along the gumline compared to a manual brush felt accurate in my experience. My hygienist commented on reduced plaque buildup at my six-month cleaning after switching to this brush. The smart pressure sensor slows the motor when you press too hard, protecting your gums automatically.

Three modes (Daily Clean, Sensitive, and Whitening) cover the basics well. I appreciated that Sensitive mode genuinely felt gentle, not just a marketing label. The Whitening mode uses a different oscillation pattern that left my teeth feeling polished.

The included travel case is sturdy and has survived multiple trips in checked luggage. Two brush heads in the box give you about six months of use before needing replacements. The LightRing Timer provides a visual celebration when you hit the two-minute mark.

The main downside is battery warning. The brush has no low-battery indicator. It simply dies mid-brush without warning, which happened to me twice during testing. I learned to charge it every Sunday as a routine to avoid this issue.

Entry Into the iO Ecosystem

If you have been curious about iO technology but hesitant about the price, the Series 3 Limited is your gateway. It delivers the same magnetic micro-vibration cleaning as the Series 7 and 9, just with fewer modes and no app connectivity. You still get the superior plaque removal that makes iO worth it.

On Prime Day, this brush typically drops to around $60 to $70, making it one of the best deals in the iO lineup.

What You Lose Compared to Higher Models

Compared to the iO5 and Series 7, you lose app connectivity, two cleaning modes, and the more detailed pressure feedback. The pressure sensor on the Series 3 works but does not differentiate between too-soft and too-hard the way the Series 7 does. It only alerts when you press too hard.

For many users, these missing features will not matter. The core cleaning technology is what makes the iO line special, and the Series 3 delivers that fully.

8. Oral-B iO3 Clean and Protect

The iO3 Clean and Protect offers iO technology at the most affordable price point in the iO family. I was impressed by how close the cleaning performance came to the more expensive iO5 during side-by-side testing. The three modes (Daily Clean, Sensitive, and Whitening) cover the essentials that most users need.

The visual pressure sensor on this model is bright. Really bright. The green LED ring that signals proper pressure lights up your entire bathroom. For night brushing, some users find this disruptive. I adapted to it within a week, but it is worth knowing if you brush in a dimly lit bathroom.

The LightRing Timer celebrates when you complete the dentist-recommended two minutes. The refill change alert is a genuinely helpful feature that reminds you when it is time to swap brush heads. These small touches make the iO3 feel more premium than its price suggests.

I noticed healthier gums within the first week, consistent with the product claim. The oscillating-rotating motion combined with iO micro-vibrations delivers a noticeably different clean than traditional Oral-B brushes. My teeth felt smoother after each session.

The lithium-ion battery holds a charge well during regular use. However, some long-term reviewers note battery degradation after a year of daily use. At the Prime Day price, the value proposition is strong even if you need to replace it after 18 to 24 months.

Night Brushing Light Issue

If you brush before bed in a dark bathroom, the green pressure sensor light is something to consider. It illuminates the room significantly. Some users solve this by cupping their hand over the light ring, but that defeats the purpose of the visual feedback.

If this is a dealbreaker, the iO2 and the standard iO Series 3 use a less intense sensor system that may work better for night brushing.

Value Position in the iO Lineup

The iO3 sits between the iO2 and iO5. You get the LightRing Timer and refill alert that the iO2 lacks, but you miss the app connectivity of the iO5. On Prime Day, the price difference between the iO3 and iO5 often shrinks to under $20, which makes the iO5 tempting for the extra modes alone.

Our recommendation: if the gap is under $15, upgrade to the iO5. If it is larger, the iO3 delivers excellent value for the core cleaning experience.

9. Oral-B iO2 Starter Kit

The iO2 Starter Kit is designed for one purpose: getting you into the iO ecosystem at the lowest possible cost. At its regular price, it is already the cheapest iO brush available. On Prime Day, it becomes almost impulse-buy territory. I found the cleaning performance to be remarkably close to the more expensive iO3.

The automatic pressure sensor is the key feature here. When you press too hard, the brush automatically slows down and signals red. This is the same core sensor technology as the rest of the iO line. It genuinely changed how I brush within the first few days.

The three modes (super-sensitive, gentle, and daily clean) are well-calibrated. Super-sensitive mode is perfect for anyone with receding gums or recent dental work. I used it exclusively for a week after getting a filling, and it was gentle enough to avoid irritation.

The motor is quieter than I expected for a budget iO model. It produces a low hum rather than the aggressive buzz of older Oral-B brushes. The Night Black finish looks sleek on a bathroom counter.

One important note: some users report that the iO vibration pattern causes mild headaches. This seems to affect a small percentage of people and may be related to the micro-vibration frequency. If you are sensitive to vibrations, test the brush within the 30-day return window.

Starter Kit Limitations

The Starter Kit is called that for a reason. You get the brush, two heads, and a charger. No travel case, no brush head cover, no extra accessories. If you travel frequently, you will need to buy a case separately or upgrade to the iO3 or higher.

The timer also behaves differently than other models. Instead of shutting off at two minutes, it continues to pulse, reminding you that the recommended time has passed. Some users prefer this; others find it annoying.

Replacement Head Strategy

iO replacement heads are proprietary and cost more than standard Oral-B heads. Plan on spending about $30 to $40 per year on replacements. The best strategy is to buy multipacks during Prime Day alongside the brush to maximize savings.

The brush is compatible with all Oral-B iO replacement heads, giving you options for sensitive cleaning, whitening, and deep clean preferences.

10. Oral-B iO Limited Simple Clean

The iO Limited Simple Clean lives up to its name. This is the most user-friendly iO brush I tested, designed specifically for people switching from a manual toothbrush for the first time. The single-button operation makes it foolproof. Press once to turn on, press again to change modes, press and hold to turn off.

I handed this brush to my mother, who has used manual toothbrushes her entire life, and she adapted within two days. The pressure sensor gave her confidence that she was not damaging her gums. The quiet motor did not startle her the way older electric brushes would have.

The three modes (super-sensitive, gentle, and daily clean) provide just enough variety without overwhelming new users. The automatic pressure sensor slows the brush and flashes red when you press too hard, which is the most important safety feature for first-time electric brush users.

The included travel case is a nice bonus at this price point. The case is compact and fits easily in a carry-on bag. The long-lasting battery means you can travel for a week without worrying about charging.

The one feature I wish it had is an automatic shut-off at two minutes. The brush continues running until you manually turn it off. The 30-second zone alerts still fire, but you need to pay attention to stop at two minutes yourself.

Best First Electric Toothbrush

If you or someone in your family is making the jump from manual to electric for the first time, this is the brush I would recommend. The learning curve is minimal, the pressure sensor prevents the most common mistake (brushing too hard), and the cleaning performance matches brushes that cost twice as much.

The iO technology means you are not compromising on cleaning power by choosing the simplest model in the lineup.

How It Compares to the iO2

The Simple Clean and the iO2 share the same core iO technology and similar mode counts. The Simple Clean adds a travel case and a slightly different button design. The iO2 has a slightly more modern aesthetic. On Prime Day, pick whichever is cheaper, as the cleaning experience is nearly identical.

Both models use the same replacement heads, so ongoing costs are the same regardless of which you choose.

11. Oral-B Pro 1000 2-Pack – Best Deal for Couples

The Pro 1000 2-Pack is the smartest purchase for couples and families during Prime Day. You get two complete electric toothbrushes in one box, each with its own color-coded handle. The per-brush cost drops significantly compared to buying individually, and the cleaning performance matches the single Pro 1000 exactly.

My partner and I used this set for six months before I started testing other models for this guide. The color coding prevented the classic mistake of grabbing the wrong brush from the charger. Both brushes performed identically in terms of cleaning power and battery life.

The 3D cleaning action delivers the same oscillate-rotate-pulsate motion that made the single Pro 1000 the number one best seller. Each brush includes three cleaning modes and a gum pressure control that slows the motor when you press too hard.

The shared charger design is actually convenient. Both brushes use the same charging base, so you only need one outlet. The charger is a bit bulky compared to newer models, but it works reliably.

The main trade-off versus newer iO models is the cleaning technology. The 3D action is excellent and dentist-recommended, but it does not have the micro-vibrations of the iO line. If you and your partner want the absolute best clean, consider two iO2 Starter Kits instead. But for most people, the Pro 1000 2-Pack delivers more than enough cleaning power at a fraction of the cost.

Cost Breakdown for Two People

On Prime Day, the 2-Pack typically drops to around $60 to $70. That works out to $30 to $35 per person for a dentist-quality electric toothbrush. Compare that to $50+ for a single Smart 1500 or $100+ for an iO model. For budget-conscious couples, this deal is hard to beat.

Replacement heads are also affordable since both brushes use standard Oral-B heads available in multipacks.

What to Know Before Buying

The charger takes up a standard outlet space and cannot be wall-mounted easily. Battery life is about 7 to 10 days per charge, which is shorter than the Smart 1500 or iO models. Neither brush includes a travel case.

Despite these limitations, the cleaning performance per dollar is outstanding. This is why the 2-Pack maintains a 4.5-star rating across 5,000+ reviews.

12. Oral-B Pro 100 Battery Powered – Cheapest Option

The Oral-B Pro 100 Battery Powered is the cheapest electric toothbrush on this list, and sometimes the cheapest option is the right one. I keep one of these in my travel bag as a backup. At under $20 on Prime Day, it delivers a genuinely better clean than any manual toothbrush.

The CrossAction brush head uses the same round design as Oral-B’s rechargeable models. The bristles are angled at 16 degrees to reach between teeth. While the motor is less powerful than a rechargeable brush, the oscillating motion still removes significantly more plaque than manual brushing.

I tested this brush for two weeks of daily use. The two AA batteries that come included lasted the full test period and were still going strong. The 2-minute timer helps ensure proper brushing time, though there are no 30-second quadrant alerts like on the rechargeable models.

For travel, this brush is unbeatable. No charger to pack, no worries about voltage compatibility, no lithium-ion battery concerns at airport security. Just toss it in your toiletry bag with a spare set of batteries.

The limitation is power. The battery-powered motor produces fewer oscillations per minute than a rechargeable brush. You will get a good clean, but not the deep, dentist-fresh feeling of an iO or Smart 1500. For the price, it is an excellent value.

Best Use Cases for a Battery Brush

This brush shines in three scenarios: as a first electric toothbrush for kids or teenagers, as a dedicated travel brush, and as a backup for when your rechargeable brush dies unexpectedly. At Prime Day pricing, buying two makes sense so you always have a spare.

It is also a good option for anyone who wants to try electric brushing without committing to a $50+ rechargeable model.

Replacement Head Compatibility

The Pro 100 works with the same standard Oral-B replacement heads as the Pro 1000 and Smart 1500. This means you can use CrossAction, Sensitive Clean, 3D White, and other popular heads. Replacement head costs are the same as any non-iO Oral-B brush.

Note that iO replacement heads will not fit this model. The Pro 100 uses the traditional push-on head design.

How to Choose the Best Oral-B Deal on Prime Day 2026

Navigating 12 different Oral-B models during Prime Day can feel overwhelming. Here is our framework for choosing the right brush based on what matters most to you, including the long-term cost of ownership that most guides skip entirely.

iO vs Non-iO Technology

Oral-B currently offers two cleaning technologies. Traditional 3D cleaning (used in Pro 1000, Smart 1500, and Pro 100) oscillates, rotates, and pulsates. iO technology adds magnetic micro-vibrations to the oscillating-rotating motion, delivering a smoother and more thorough clean.

Our testing consistently showed that iO brushes leave teeth feeling smoother after each session. The micro-vibrations reach areas that traditional oscillating brushes miss. However, the non-iO brushes still deliver excellent plaque removal and cost significantly less upfront and ongoing.

If budget is your primary concern, the Smart 1500 with 3D cleaning gives you 85% of the iO experience at half the price. If you want the best clean possible, go with any iO model.

Pressure Sensor Importance

Dentists consistently rank pressure sensors as one of the most important features in an electric toothbrush. Over-brushing damages gums and causes recession over time. Every brush on this list has some form of pressure control, but they differ significantly:

The iO Series 7 and 9 offer the most advanced system with red (too hard), white (too soft), and green (just right) visual feedback. The Smart 1500 uses a 360-degree light ring that is almost as effective. The Pro 1000 uses motor slowdown feedback without visual cues, which is less intuitive but still protective.

Long-Term Cost of Replacement Heads

This is the hidden cost that Reddit users constantly flag. Over two years, replacement heads can add $40 to $80 to your total cost depending on the model:

Standard Oral-B heads (for Pro 1000, Smart 1500, Pro 100) cost $5 to $6 each and need replacing every 3 months. Annual cost: about $20 to $24. iO replacement heads cost $8 to $10 each with the same replacement schedule. Annual cost: about $32 to $40.

That difference adds up. Over five years, iO ownership costs an extra $60 to $80 in heads alone. Factor this into your purchase decision, especially if you are buying for multiple family members.

Prime Day Deal Strategy

Oral-B Prime Day deals typically follow a pattern. The deepest discounts (40 to 50% off) appear on mid-range models like the iO Series 3 and iO5. Entry-level brushes like the Pro 1000 see smaller percentage discounts (20 to 30%) because they are already priced low. Premium models like the Series 7 and 9 get 25 to 35% off, which represents the biggest dollar savings.

Our advice: check prices early on Day 1, set up deal alerts for your top picks, and be ready to buy within the first few hours. The most popular models sell out before Day 2. Also look for lightning deals on replacement head multipacks, which offer excellent stacking value.
