    Very good brush and system!
    This toothbrush exceeded my expectations. The charging base is a well thought out system that includes a charging base, a cup for rinsing and a slot to sanitize your brush with UV light, and the kit also comes with 3 toothbrush heads to start with. The brush itself is powerful and makes my teeth feel really clean, almost like a professional cleaning at the dentist. The pink color is also super cute (a nice plus), and the price is very reasonable, especially if using the coupon for $29 that they run sometimes.

    It works!
    I tried these on my teenage son who has pretty yellow teeth after braces. You can’t really tell in pics but in person they made a difference. He hasn’t had any odd side effects or sore gums from using them and said they were easy to use. He wears them for the recommended amount of time although started lower the first time to make sure he wasn’t allergic or anything. But so far great product and we are happy with it!

    Work about as well as drugstore brands.
    These are at least as good as the national brands at a fraction of the cost. They stick on easily and used as directed will whiten your teeth a few shades over the course of treatment.
