Amazing Water Flosser

I started with the C10 for travel. It was awesome and so I got the C30 for home use. I hardly ever flossed until now. I can't believe how clean my teeth feel after water flossing. It's now my daily routine.

It’s good

I give it a four stars instead of five stars. The small problems is press the botton will be more difficult to turn it on and off instead of push the levels botton would be much easier. The floss tubes are more like water. Not like any kind of floss with a sting on the tubes. The other than that is good.

Thank you for sharing your feedback and for giving us four stars! We’re glad to hear that you’re happy with the flosser overall.
We understand your point about the power button. The button is designed to control the device separately from the mode settings, but we appreciate that the operation may feel less intuitive depending on how you use the flosser.
Regarding the flossing experience, the tips are designed to deliver a focused, pulsating stream of water to clean between the teeth and along the gumline. Unlike traditional string floss, they use water rather than a physical thread, so the sensation and water flow can feel quite different.
Thank you again for choosing usmile and for sharing your experience!

Good for braces! wish I had this years ago

My daughter has braces and keeping her teeth clean has been a constant battle. We bought the C30 based on a recommendation and it's been a game changer. The orthodontic tip that comes included is perfect for cleaning around the brackets. She says the water pressure is strong enough to feel like it's actually doing something but doesn't hurt. Would highly recommend for anyone with orthodontic work.
