It's very easy to use, and works really well as a toothbrush. My dentist likes it. Only issue: I found the app a little funky and hard to use. I'd recommend it, but I'm not sure it clean that much better than somewhat cheaper models.

Fantastic, my dentist actually asked what I use to brush my teeth. The dentist visit took like 5 minutes.

Works really well, I was surprised that this little toothbrush even tells you when to switch out the heads. But just keep in mind the brush heads are not cheap.

Only giving it four stars as I had to replace my first one just shy of two years. Coincidentally it totally died on me within a very few days of the warranty expiring. But, I do very much like my toothbrush. It does an excellent job. And, it’s very pretty.

Bought the toothbrush as a gift for my sister. Really happy with the product! The battery life is really long (about whole week) even if you using 3 or 4 times per day. Thanks

My dentist recommended this tooth brush and I will never go back to a regular one the type of clean you get with this brush is invigorating.

It's a great electric toothbrush, but after I bought it I realized I really didn't want the bells and whistles of the "smart connected" features. It nags when heads get swapped on and off, I did not use any of the other smart features.

lots of options with this product, excellent brushing quality, the app is very helpful for observing the thoroughness of the cleaning. like the charger and the stand for keeping the brush at the sink between uses

Waited for quite some time to finally buy this thing. Glad I did. It works exactly as expected. Really cleans your teeth. The app works great with it so you can keep track of your brushing habits.

This replaced an old Sonicare tooth brush. There is no comparison. I thought my old tooth brush was good, but i used this for a week before my regular dental cleaning and there was almost no plaque!

I love sonicare. Now with pressure feedback. My teeth are always clean with a sonicare but my dentist said I was brushing too hard. With this brush I hope to have a better experience at the dentist next time.

I bought it to replace the one lost in the Camp Fire. It is in some ways an upgrade, comes with different brush head, but the travel case doesn't act as charger like the previous model.
