I went through two of these in less than two years and am going back to oral-b. The original brush I ordered worked well for a few months and then slowly started malfunctioning (turning off in the middle of brushing despite being charged) until it eventually stopped turning on at all. I filed a warranty claim and they sent me another. It did the exact same thing. The app also doesn't work well and had issues syncing with the brush to actually record brushing and get points. Don't waste your money.
It’s great! Gentle on my teeth and a nice hybrid between manual brushing and electric. Sometimes I feel like an electric toothbrush doesn’t get a great clean but this definitely does!
Very happy with my purchase, I've had the older version for many years now and it finally began going down hill. Even a new, fresh battery wasn't helping. I wanted to upgrade to rechargable anyways so it all worked out. I can't believe this thing has a THREE MONTH battery charge! Wow. 0~o I love the app and tracking too! Thank you for an awesome toothbrush!
