  • Not as weak as they say
Size: 1 Count (Pack of 1) Color: White
This is my 1st electric toothbrush. I ordered it over the oral b smart 1500 because it's cheaper and I found more people who swear by it than oral b. Later on, I read comments where people who have this 4100 for 10+ years say that the newer 2021 version has only half the power of the old version. Someone on reddit showed images of the inside of the new and old versions and the new version has a small plastic toy-like motor, while the old version has a big copper-wrapped motor and an old version user said "now I understand why the new version is lighter and less powerful". I was disappointed on the new version and tried to cancel the order but I couldn't. Once it came, I decided to try it and to my surprise, it brushes my teeth way better than my manual soft-bristled and hard-bristled toothbrushes(I use both manual brushes daily compared to my daily usage of the electric toothbrush 4100 C2 head of medium bristles. If you have gum sensitive issue, buy the S sensitive or G2 optimal brush head. If you want hard-bristled, buy W diamondclean brush head). I don't know how good the old version was but this newer version definitely brushes better than any manual toothbrush unfortunately it doesn't not come with a travel case. Update 5/16/2024: I bought the Oral B smart 1500 because it was on sale and I wanted to see how better it is compared to the sonicare. The oral B package looks nicer and bigger than the Sonicare but upon opening the smart 1500 package, I saw hair all over the toothbrush. I did read many customers saying on reddit that their Oral b toothbrush were repackaged, but I can't believe I'm a victim of this nastiness. It also took 2 weeks to reach me from Hawaii and since it says "made in China", I think the seller is located in China. I'll return this and I'll advise you to buy the Sonicare instead of the oral b if you don't want to be cheated receiving a used-repackaged toothbrush. Update 05/22/2024: On 05/17/24, I bought the Oral b smart clean 360 which has exact power as the smart 1500 that I returned but the smart 360 has 5 modes and a button to change the mode while the smart 1500 has 3 modes and no button to switch between the modes. The advantage of the oral b smart clean 360 is that the brush heads cost is cheaper than the Sonicare 4100 and I find it better at whitening my teeth than the Sonicare. That's all the advantages there. The things that I don't like with it are many, so I'm just going to name the most annoying ones: 1) The brush heads are too big compared to the Sonicare(see picture): Putting Oral b brush heads in my mouth is like putting a golf ball in my mouth(my head and mouth are wider than the average US male). 2) The brush heads have holes(see pictures) that trap saliva+toothpaste and creates more noise when the brush handle needle rotates in the presence of the liquid mixture, and moisture will be also trapped easily in the holes(most customers complain about Oral b brush heads design. Oral b corrected the needle issue with the IO version but the IO introduced a shallow hole which now traps moisture in the brush handle). When I'm using the Oral b with no choice but to have my mouth wide-open, it forces my mouth to produce more saliva which gets mixed with the toothpaste and enters the brush head and creates more noise. 3) Rattling noise: The Oral b smart clean 360 isn't as noisy as people say. It's the quality of the noise the problem. It's a very unpleasant rattling noise as if you're hearing an old car engine with broken parts in it. That noise gets worse when liquid enters the brush head holes. 4) The charger is not round like a perfect circle: You must put the Oral b brush handle in a specific position to charge it and if you place it wrong, it'll fall and might break. 5) The Daily Clean mode is rough and combined with the big brush head the experience is bad, but the smart clean 360 has more mode which make it smoother and better than the smart 1500 but not as good as the Sonicare 4100. 6)It has no auto-stop mode: You keep brushing without knowing how long you have been brushing your teeth. To summarize, the oral b non-IO brush heads are cheap but very badly designed for a pleasant toothbrushing. I won't recommend it if you're shorter than 6 foot tall or have a small mouth. ... show more

  • Wish I Had Tried an Electric Toothbrush Sooner
Size: 1 Count (Pack of 1) Color: White
This electric toothbrush has been a bit of a “where has this been all my life?” purchase for me. It cleans very well, but more importantly, it helps me control both the pressure and the amount of time I spend brushing. Otherwise, I tend to keep brushing for far too long—sometimes close to ten minutes. My teeth feel very clean after using it. I’m still getting used to the sensation since this is my first electric toothbrush, but so far I think it’s a very good choice for a first one. ... show more

  • Great small electric toothbrush
Size: 1 Count (Pack of 1) Color: White
Convenient size, efficient and holds charge. Only drawback is that it doesn't come with the adapter for wall charging - as disclosed in the ad.

  • Too bad it lasted only 3.5 years
Size: 1 Count (Pack of 1) Color: White
Ordered Dec 2023. Toothbrush is now worn out 3.5 years later. A little disappointed in the longevity for a $50 toothbrush. The toothbrush would not turn off even though the metal button would click appropriately. When I was finally able to get it turned off it would turn itself back on randomly and eventually ran itself out overnight. The body started heating up sobI placed it ina coffee cup in the sink to prevent fire. Although this is the one I purchased, mine is not identified by the name Sonicare on the brush handle. Perhaps a knockoff was sent. I am ordering another one due to having leftover replacement brush heads. Will see what the longevity of the new one is a and report back. ... show more

  • Not long lasting.
Size: 1 Count (Pack of 1) Color: White
This item does not last very long. Iffy quality. The price is great for what it is, and it has what feels like a solid vibrational capacity, though. I bought this three years ago, and it became dysfunctional. The on/off button wore down to its metal interior, and then that button became unreliable, not working 60%+ of the time. I am debating buying another one when other options exist with maybe a higher price point but longer durability. ... show more

  • Philips Sonicare 4100: Your Smile's New Best Friend – A Must-Have for Superior Clean!
Size: 1 Count (Pack of 1) Color: White
As someone deeply invested in maintaining optimal oral health, I'm always on the lookout for products that genuinely deliver. After experiencing the Philips Sonicare 4100 Rechargeable Electric Toothbrush (Model HX3681/23), I can confidently say this isn't just another gadget; it's a game-changer for your daily brushing routine. With an impressive 4.4 out of 5 stars from over 46,000 reviews and being an Amazon's Choice with 50K+ units bought last month, it's clear I'm not alone in my enthusiasm! From the moment you unbox this sleek white device, you appreciate its ergonomic design and lightweight feel. But the real magic happens when you start brushing. Here's why the Philips Sonicare 4100 stands out and why it's a smart investment for your oral health: Unmatched Plaque Removal: Forget your manual toothbrush! This sonic powerhouse is clinically proven to remove up to 7 times more plaque. The 31,000 brush strokes per minute gently yet effectively break up and sweep away plaque, leaving your teeth feeling incredibly clean and smooth – a noticeable difference from day one. This directly addresses the core need for effective cleaning. Gentle on Gums, Smart on Pressure: One of my biggest concerns with electric toothbrushes has always been applying too much pressure. The Sonicare 4100 brilliantly solves this with its built-in pressure sensor. If you press too hard, it automatically warns you and reduces vibrations, protecting your gums from damage. This feature alone provides immense peace of mind and makes it ideal for sensitive gums. Master Your Brushing Technique: The SmarTimer and QuadPacer are invaluable. The SmarTimer ensures you brush for the dentist-recommended two minutes, while the QuadPacer guides you to brush each quadrant of your mouth equally. This takes the guesswork out of brushing and helps you develop consistently good habits. Long-Lasting Convenience: With a 14-day battery life on a single charge, this toothbrush is perfect for travel or for those who simply don't want to constantly think about recharging. The included USB charger makes it easy to power up wherever you are. Aesthetic Appeal: Beyond its performance, the sleek white design is a welcome addition to any bathroom countertop, blending seamlessly with modern aesthetics. The Verdict: The Philips Sonicare 4100 isn't just an upgrade; it's an essential tool for anyone serious about elevating their oral care routine. It combines advanced technology with user-friendly features, delivering a superior clean while protecting your gums. Considering its current 20% savings, bringing the price down to just $39.96 from $49.96, it offers exceptional value for such a high-performing device. If you're ready to experience a truly effective, gentle, and smart brushing experience, the Philips Sonicare 4100 is highly recommended. It's more than just a toothbrush; it's an investment in a healthier, brighter smile. ... show more

  • Replaced my old Series 2 Sonicare with this one and can highly recommend this 4100 Model.
Size: 1 Count (Pack of 1) Color: White
I was replacing my "old" Phillips Sonicare, specifically the HX6240, which was a series 2 model. Loved it. I found newer brands of electric toothbrushes seemed to be including 2 features I did not want, sending my data; and, reminders to brush a new area every 20 sec for 2 minutes. The latter called Brush Pacer results in 6 reminders. I prefer 4 reminders, the Quad Pacer Timer, 4 - 30 sec increments. Easier to keep track of where I already brushed. This new 4100 had the Quad Pacer, was not info invasive, and I could use the same brush tips I liked. The Lithium Ion battery on this new one lasts longer than the old NiMH one. It can sit on a "similar looking" charging base to the old one. But the new model is charged via a USB type A cable base and cord. You can use any standard USB charger you already own for phones or tablets. This model includes 2 Pressure sensitive settings, which is all I need. It is lighter and has a slimmer profile. One unexpected thing is that you can actually charge the new model on the older model's base. My spouse still uses the older model, and when we have extended travel together we take just one charger. Its turned out to be the perfect replacement electric toothbrush for me. (Photos: Older Model is on your left.) ... show more

  • 14 months old and power button is getting wonky
Size: 1 Count (Pack of 1) Color: White
I bought an earlier model of this one in 2018 and replaced it with this one in 2025. Lasted 8 years. This one, which I've used for 14 months, is getting increasingly hard to turn on. The rubber over the power button is chipping and I now have to push very hard in the center with my fingernail to get it to go on. Used to be an easy finger press. Not sure what the problem is. I do not appreciate the shorter battery life. I have to charge it about every 2-3 weeks where the old one would go for a whole month until it suddenly stopped holding a charge. Brushingwise it's the same as the old one, low and high speeds, no complaints there. ... show more
