    Amazing toothbrush, it has apps for you to clean, many modes for you to select, and after brush, I feel my teeth is much cleaner than the diamond clean.

    Bought this for my daughter at her dentist's recommendation and she loves it. The app helps her to better identify areas she may have missed and also reminds her to brush. It's great!

    One of the best toothbrushes I’ve used. It cleans way better than the sonicare model. Feels like I’ve been to the dentist after every brushing

    I bought this for my wife who loves pragmatic technology! She’s very into her health and well-being so it’s safe to say that this little tech-enabled toothbrush has brought her some fun and happiness when it comes to dental health (usually a very underserved aspect of health) I am giving it 5-Stars because she didn’t have even one negative thing to say about the experience. However: I use a good ol’ toothbrush and honestly can’t share the excitement. For those looking for the “most complete” clean, this is it.

    Works Well to Improve Brushing

    The toothbrush and real-time app work well for me. However, if you need to pause the brushing momentarily around the two-minute mark, the app ends your brushing. The other option if you need to pause momentarily is to take the active toothbrush out of your mouth, but then toothpaste goes everywhere. An additional area that could be improved would be better onboarding with an explanation of how to move to different modes. That being said, the small improvements that are needed would not stop me from recommending the item.

    Overall I like the toothbrush and all its capabilities. I wish the app did not have to be open in order to record a cleaning session though. I hope the app continues to adapt and get better with time. I find myself brushing my teeth more thanks to it.
