    Quick charging, good app integration, tracking is a bit touchy but if you go slow (as you should anyway) it works well.

    Great toothbrush. The vibrations take a bit of getting used to but once you do, its awesome. However, I did return this to buy a two-pack for cheaper the price and a big box store.

    Great toothbrush. The app helps learn how long and what pressure to get all your teeth clean. Replacement heads are very expensive.

    Worst purchase of the year. For the price, this isnt worth it. The app is ok. Does a decent job with tracking your brushing on each quadrant. But you have to hold the phone up to see the progres. Paired with how messy it is, using the app becomes not worth it. The battery dies mid brush, multiple times in a 2 minute session. Says its at 100% when starting a brush session but dies to 0% in 15-20 seconds. I’ll never buy one of these again.

    Pretty great and fun to use, I would say one down side is the AI with the phone doesn’t match sometimes, I’m brushing a specific area and the phone will say I’m brushing something else.

    Best toothbrush I've ever used. At any age, it's important to brush correctly. By using the phone app, you can see where you need extra brushing, you are scored every time you brush.

    Great Toothbrush! The 3D guide in the app is terrific, although some of the time the app thinks the Toothbrush is brushing the wrong area.
