    I’ve had an Oral-B alternative for the longest time and the dentist recommended that I switch to the sonicare. Because of the vibrating action, it’s a lot gentler and more effective on your gums.

    The toothbrush and all features in the app are great. I do not find myself using the app. The features are neat but don’t take the time to open app every time I brush my teeth. I also haven’t mastered brushing without toothpaste flying everywhere. If you know the trick please share. Otherwise I recommend brushing in the shower as not to make a huge mess around the sink.

    Great out of the box but started making loud noises and when I removed the brush the connection point was really loose and was creating the loud noise. This is the 2nd toothbrush of this model I've purchased and the 1st one is still running fine 2 years later. Must have been a faulty one. Best Buy was great with returning it and getting a new one.

    The toothbrush itself works great, holds charge for a long time. Only issue is that you need to buy a separate tongue cleaner. Brush head does not work good for that
