    I bought this brush because my dentist told me i brush to hard and that effects your gum health. Been using this for a few weeks now and my teeth fell clean after each use and the moonier sensitivity i had in some gum areas is pretty much non existent. If you care about your oral health pick this up.

    Great product! Cleans teeth well. There are two of us who use it. And it doesn’t seem to last long. I feel like we are buying a new one every few years. If that’s all it’s supposed to last. Then it’s great. It really does an amazing job of cleaning our teeth. And it travels well!

    Excellent toothbrush! It does everything that it is advertised to do. Electric toothbrushes have a tendency to be harsh on your gums. However, Philips Sonicare has a gum protection selection. Great buy! You will not be disappointed.

    This toothbrush communicates with my phone and shows me the job I have done. Hint, right handed, the left side of my mouth was better taken care of than the right side. Who would have thought? It knows where I brush, how hard, how long. And shows me on the phone, coaches me … WOW

    Great product. I had an older Sonicare that had to be replaced so I chose this one. The charger is less cumbersome and I have room for it on my countertop. I also like the dark color the precuts comes in now.

    Got this toothbrush because my wife got the oral-b. Both are very similar and both apps work great. The only difference in the 2 is the shape of the toothbrush. I like the Phillips charging glass better.

    Diamondcare sonic toothbrushes from Philips are a game changer. If you are using a contact brush (oral b) you are incurring needless cavities. No comparison between the two approaches to dental health.

    The mobile guide is very helpful with showing how to brush the right way for the best results and to extend the toothbrush head's life. Great features and my teeth have never felt cleaner and healthier.

    After about 5 years, my old Sonicare batteries couldn't hold a charge. I wanted to try the newer version, and am satisfied. Although, I don't really need the extra options with this version. My dental hygienist, and dentist, have very little work to do since switching to Sonicare!

    There are features you won't use, but after the right dentist visit, you'll suddenly need. I love how the handle reads the brush head and adjusts the program automatically

    My first smart electric toothbrushes. I used to think it is unnecessary sepending $230 for this product. After my co-worker told my his great experience, I tried it and loved it. I felt my teeth is cleaner than ever. I get compliment from people all the time. Get one and smile!

    I've used Philips Sonicare toothbrushes for many years. This model looks great and feels great in your hand. I love the white LED lighting and the unit's LED lighting alerts when you are using too much pressure. The unit also charges quickly and comes with a great travel case.
