    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.

    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.

    A very good toothbrush that with the companion phone app manages the information for your oral health. I have not found a netter app and brushing system.

    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!

    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.

    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.

    For the price paid. I would say that the it is a really good value. The Tooth brush is easy to use and has a great app that allows you to track the right areas to attack when keeping your mouth clean.

    I was looking for a new electric toothbrush and picked this up at Christmas time. It works great and I really enjoy all the bells and whistles it comes with. The only complaint I have is that you need to charge it by putting it in like a glass, which is kind of unusual. Other than that, I'd highly recommend this product.
