The brush is not powerful enough. The motor is too loud. Its a good idea but product needs fine tooning. I returned it.
No, I would not recommend this to a friend.

We appreciate your feedback. The toothbrush portion provides 30,000 brush strokes per minute and has been proven to be effective. The Sonic-Fusion is a motor-driven appliance, and as with other common household motor-driven appliances, some noise is normal. Again thank you very much for your comments, we rely on customer's feedback heavily when designing new products!
I think it works well. When my wife and used ours together and thought them broken until we learned about frequency disruption. And the water “leakage” from my mouth is somewhat messy.
Does a great job of cleaning your teeth. There was a learning curve though for me as I did a lot of spraying of myself and the bathroom until I figured out how to hold it correctly.
