    Great tool for through brusing and brush heads for cleaning all around your mouth that will make you feel you brushed your teeth in a more complete fashion then a regular manual toothbrush. Plenty of different brush settings depending on the brush head your using.

    Makes brushing easier and more fun

    So I was never big on the "smart" aspect of teeth brushing until I got the new toothbrush. The app is really easy to install and use and provides helpful information as you are brushing to make sure you are getting all the parts of your mouth. It also makes it easier to make sure you are brushing for at least 2 mins which I think is very beneficial without having to set a timer.

    This is an excellent product. I bought for me 13yo son who hadn’t been brushing properly. The results have been positive, he is now spending longer brushing he s teeth and it shows (my dad is a dentist). I haven’t used it personally, but I have a previous model that I am happy with. If looking to upgrade from one that already uses diamond heads, I’d pass. But if you are going to buy a new electric toothbrush this is the one you should get. I hope this helps

    I get more cleaning done in 2 minutes than most do all day with a traditional toothbrush. Teeth not only feel great, they are smooth and bright.

    Bought this for the wife and she loves it. Takes a bit of getting used to with being the first toothbrush like this, but after a few weeks she loves it. Highly recommend to anyone looking for a great clean feeling!

    Excellent job for tooth and gum cleaning - feels like my mouth has been pressure-washed :) I think the only major difference between this and the cheaper model is the "whitening" mode which is just the regular brush mode with two extra focused sessions on the upper and lower front teeth. The buttons also look slightly different, but functionally it seems the same.

    This is my second Sonicare toothbrush. I purchased this one as a replacement after my last one started going out a little after 2 years. The app is super easy and really helpful to get the best brush in. The new feature that tells you if you're using too much pressure.

    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!

    I did not know how much better I could learn to brush my teeth. The app teaches you how to correctly brush you teeth. I thought this was very expensive when my wife bought it but as I have learn to brush better it is defiantly worth it.
