    I'll be honest - this thing is overkill for me. It not only has three different styles of heads based on your needs, but also can be used with the corresponding app to show you spots you're missing when brushing AND it lights up when you're brushing too hard. This thing is incredible. If I could do it again, I would get something a bit more simple, but this is a high-quality product that will very much appeal to those looking to get as much data and insight into their oral hygiene.

    Great toothbrush worth the price

    Excellent design and great functionality. This is my first electronic toothbrush in years, and I opted to go for quality VS basing my decision on price alone. I am glad I made the purchase. On something related to your health and something that is used at least twice per day and with the potential to be functional for years and years to come, it became easy to justify spending $200 for this product. The "charging glass" and travel case it came with are very nice / high quality and an innovative and cool/fun design.

    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

    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.

    Been using sonicare for 22 years. Went from the cheapest to whitening to flexcare to this. The previous upgrades were a big difference. The vibration speed etc. Coming from flexcare ($99) to this ($150), not so much. Much better battery and construction though.

    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.

    ...Out of business! 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'.

    I have not had my first dental visit yet after getting the toothbrush. My teeth do feel cleaner than with my regular toothbrush. I cannot say if this brush is better than a Cheaper version. I also don’t like the vibrate feeling when I’m brushing.

    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.

    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!
