    So far I’m Enjoying it. It did take me some time to learn how to use it effectively basically letting the tool do the work Instead of manually brushing

    Best clean feeling i've had in forever since moving from manual brushing. My dentist was impressed by the cleanliness of my teeth, was less impressed by how irritated my gums were from using the "Gum Health" setting. Won't be using that mode again. Haven't used teeth whitening mode yet.

    This electric toothbrush is by far the best one I have used. I've tried them all before and think this is the best yet. It also looks really nice in all black as it blends in with my bathroom colors.

    Great for reaching those tough areas. The last, few times to the dentist office, the dentist has had great things to say. The only change has been this toothbrush.

    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.

    It's very easy to use, and works really well as a toothbrush. My dentist likes it. Only issue: I found the app a little funky and hard to use. I'd recommend it, but I'm not sure it clean that much better than somewhat cheaper models.

    So far so good. Getting used to the app and learning to maximize the use of the product. So far no complaints. My husbands hates the glass cup/charger combo. I think it could be different/better considering the amount it costs.
