Look, it's a toothbrush. Yeah, I know exciting, huh? But if you ain't go your teeth not only do you sound like a mush-mouth but you'll be eating nothing but mush, oatmeal and the like.
This device flat works. You just need to use it! I recommend it because it works really well and I know it'll help keep my teeth where they belong - in my mouth instead of in a glass of water by the bed, LOL!
Trust me...I know what I'm doin' when I'm reviewin'.

Great toothbrush! I mean, not much to say here. It's a bit expensive. But, if you can afford it, it is significantly better than cheaper versions of the Sonniccare. So, I do recommend.

I've had several different powered toothbrushes over the last several years, but this one is the best so far. It's very powerful, but is still comfortable. No pain or discomfort during use at all. It's easier than some to keep clean between brushings (I've had trouble with some getting grime in crevises of the toothbrush body in the past). It's comfortable in the hand while brushing. The charging system is really interesting. It sits in a cup/charger. I really like this device!

I absolutely love this toothbrush. I love that it comes with 3 different brush heads and that it can detect which one is on the base. It also lets you know when you are brushing too hard and links to the app on your phone to keep you up to date and show your progress. Would definitely recommend to anyone. Worth the price.

I really enjoy the analytics that the app provides and the active monitoring while youre brushing to help maximize your brushing. The different brushing modes are really cool too (clean, whitening, gum care) depending on what your goal is. However, my one knock is that the gyros inside the handle arent quite as sensitive as I would like and it will occasionally ask you to re-brush an area youve already brushed or wont register you starting immediately.

Very powerful and good for cleaning. Need to be careful when power is on to not open your lips or you get a mess.

My wife and I bought a black and white set. Now, this is a great toothbrush, the power intensity setting is a nice feature to have and the. Build quality of course is always great from Phillips. The charging glass cup is elegant with a nice travel case.
BUT the app, is a gimmick. My wife and I don't use it at all. It's nice at first but it gets old fast and we don't follow it. Overall, this Brush with all that it comes with is fair for the price,...I feel they could go a little lower.

This was a replacement brush from the dinosaur toothbrush my ex gave me. Yeah she gave me a toothbrush??? Anyways, this prompted me to find a better electric toothbrush and I did. Sonic Care allows you to follow your daily brushing techniques and coaches you on better brushing patterns. They give you two additional brushes to the regular clean brush head. Come with a nice case for traveling. Recommend using Sensodyne toothpaste.

This soniccare diamond has made my teeth feel so clean and polished.
Also I'm amazed on how this soniccare removed hard to clean buildups and still it's removing it as I'm writing this review

This “toothbrush” is very expensive but it does a good job of cleaning and guides you to make sure you are thoroughly brushing your teeth. There are multiple brush heads, which is both good and bad as it may be a little too sophisticated for its own good. A couple weeks in and one of the programmed cleaning cycles is not working the same as it did before. I have tried removing then replacing the brush head thinking the handle will self-correct by auto selecting the brush head, but that has not worked either.

I have been using Sonicare for the last decade per the recommendation of my dentist. When my previous one died I decided to upgrade. Definitely happy with results. Technology has advanced considerably and the new app helps with everything including sending stats to your provider. A drastic difference from an average toothbrush. Convinced my friend to purchase one too.

I've been using Sonicare toothbrushes for about 20 years now, and bought this one as an upgrade to my last model, which I'd has since 2013 (I think). I MOSTLY bought this one because of the color. LOL The b lack just matched my decor better. Plus my old brush used the older model replacements which are getting harder to find.
I was a little apprehensive to drop this much money on a toothbrush as I didn't really care about any of the "smart" features. But after setting it all up (which was super easy) I really love it! I actually enjoy tracking my brushing habits in the app, and the timer that tells you when to switch to different sections of your mouth is helpful.
This brush seems more "powerful" than my older model, but still comfortable to use. I like the travel case and charging base that is included, and all the different brush heads. But the biggest reason I love this brush is the results! I drink a pot of coffee a day and am an ex-smoker. I've been using the White+ mode and I have seen a notable difference in the appearance of my teeth. Something I was not really expecting. I've been using the same whitening toothpaste I've always used with my past Sonicare, but after switching to this brush with the White+ mode, I have seen a real difference!
Highly recommend.
