    I haven't used the app as I have been lazy when it comes to smart tech as of late but this little guy has held up to being lunked around in the shower and charged via the cup it sits in for some time. I plan to check out the app soon as I feel compelled to but it does tote some cool features and I could see it working seamlessly. Would recommend.

    I’ve been using these type of toothbrush for many many years. My last one was 5 years old, I accidentally left it in a hotel. This new one definitely seems more powerful and the battery lasts a lot longer. It only needs charged every 10 days or so. In my opinion it’s one of the best ways to keep your teeth clean and your gums healthy. My dentist specifically recommended this manufacture and after a year of using it the plaque buildup was less than 15% of what it used to be for my six month routine dentist cleaning. It’s a very expensive toothbrush but if you use them for 30 years you will most likely be extremely happy that you did. Over the last 10 years I have not had one single cavity.
