    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.

    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 purchased this item in August 2020, it came with three replacement tooth brush heads. By December 2020, it stopped working and I reached out to have it replaced by the manufacturer. It was an easy replacement and for the base for the tooth brush within days. As of August 2021, it’s stopped working and was now out of warranty. There is only a 6 month warranty on the toothbrush. I had no desire to drop another $200+ on a toothbrush that was only going to function for some months. I will say that when the toothbrush was working, my dentist did commend me for superior brushing that I’ve been doing. I’ll give credit to the toothbrush for that. However, the price of the toothbrush does not justify the length of its use and the additional replacement toothbrush heads associated with it. Take the extra 5-10 minutes to thoroughly brush your teeth. Your pockets will thank you.

    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.

    Let’s be honest, this is a lot of money to spend on a toothbrush, however that being said I am impressed. Works very well with each brush and I love the technology it comes with.
