    My Husband and I both purchased this tooth brush and we absolutely love it. It has soft cleaning power which he prefers and it has intense cleaning power which I prefer. We were a little reluctant buying such an expensive tooth brush but it really is amazing. My teeth and gum health have improved so much in just a short time.

    I absolutely love this toothbrush! This is my second one so far and I could not be happier. Be mindful of the rubber membrane at the base of the head as it will easily puncture when cleaning, which will enable water into the battery chamber and render the device inoperable.

    Its a fantastic utility to have. It even warns you if you apply too much pressure. Even the dentist said that my teeth would not need cleaning as it had the plaque under control. The app tracks the time spent on the portion of your mouth and asks you to pay attention to those areas.

    Picked up 2 of these based on the suggestion of staff. Was not disappointed at all at the performance of the toothbrush. There are several positions that you can set on the brush itself which changes the vibration and intensity. Found the glass cups not to be an essential part of the package, but overall an excellent purchase.

    This product is great! My first electric toothbrush and I see why people are switching from manual to electric. I felt a big difference right away and I’m more confident with my smile. Definitely recommend this to anyone whose thinking about switching from manual toothbrush or from another electric toothbrush product.

    I love Sonicare brushes simply because they have helped me get into the habit of brushing for 2 minutes. I honestly don’t know the difference/feel the difference between the general “clean” and gym health function. This does come with multiple heads, a fantastic charging set up, and a nice travel case. I’ll have those beaut for a long time.

    It is a great toothbrush. Hook it up to your phone and it tells you that you are pushing too hard or moving too much.
