    • Have been using Sonicare for years
Size: New 4100 Color: Black
I have been using Sonicare for years but over the last year or so I did try out Quip too brushes. I found the Quip to be good but they are not as strong at the actual sonic part of cleaning teeth. I liked the size and price but didn't feel they got my teeth and comes as clean as the Sonicare. This Sonicare toothbrush is more of a basic one with two minute timer and notification so you know when to move to another section of your mouth. The toothbrush works well and does what most people need. I have used more expensive Sonicares but never really used the more advanced features. The one negative about this model is that it comes with a USB charger but not the power adaptor. So you either have to buy a power adaptor or plug it into a USB plug you may have around. That was disappointing even though it does say it on the box the description on the web page does say that it doesn't come with a power adaptor. Overall, Sonicare is the premium brand in my opinion and this model gives you what you need at a good value. ... show more

    • Powerful and versatile
Size: 1 Count (Pack of 1) Color: White
I like this toothbrush. My teeth feel really clean after using for 2 minutes. It has a load of useful features: high and low vibration modes, alert for using XS pressure, alert if the battery is running low, alert if the brush head needs to be replaced, 30 second alerts x4 to help you space your 2 minutes use and auto off at 2 minutes. It's sleek, easy to keep clean, easy to hold. My only minor criticism is that it can be hard to know the orientation of the brush in your mouth. An oval instead of round shape would help that. The battery is reported to last two weeks (I keep mine plugged in). Overall, I recommend it highly. ... show more

    • Best Purchase Ever!
Size: 1 Count (Pack of 1) Color: Pink
This is a great toothbrush! I had one for years and used it religiously. Sadly, it got old and tired and I had to replace it. With so many available, I became confused because of the big difference in prices. I thought I’d have to spend at least $200, which was what I paid for my old dinosaur many years ago. This brush is from a solid company and SO reasonable in price. The best part of the story is, I LOVE it. It cleans beautifully and is nice and light in weight. If you are in need of a new toothbrush, I HIGHLY recommend this little beauty! My old one was white, so I treated myself to pink! Black would be a great option for the guys (good Christmas gift!). I don’t usually post anything. But seriously, you can’t go wrong, and if you hate it, it can be returned. No brainer!!! ... show more

    • Great beginner Sonic brush for kids, weak for adults
Size: New 4100 Color: Black
I love my SonicCare brush, so when it was time to transition my son to a "grown up" electric brush (he was 8), I bought this version. He had a kids Oral-B before which was OK (very loud) but I've always been partial to Sonic brand for myself. It has worked very well for him, and it's whisper quiet. His teeth are clean and the dentist can tell that he does more than just using a regular tooth brush. HOWEVER, I only gave it 4 stars because while it seems to be good for kids, the couple of times that I have used it I was disappointed in the power. I don't know how Sonic rates their brushes, but this one is definitely weaker than the model I use. I wouldn't use this model for myself, but I will definitely use it for my next kid when it's time to move them up. ... show more

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

    • Great basic electric toothbrush
Size: 1 Count (Pack of 1) Color: Pink
Isn't top of the line but still does a great job of getting my teeth clean I've had this for over 2 years & haven't had any issues. Works well. Auto 2 min timer is great. Size, grip & brush heads are great. I buy the generic sonic care brush refills which are great & fit well - as well as being more cost effective. Highly recommend. ... show more
