    Im Happy with its performance. Nothing can reverse a half century of lousy dental hygiene, but it’s a good start.

    This product is strong enough and has the right amount of water flow to flush out between the teeth and along the gum line very efficiently. Love the feeling of clean teeth.

    I love this for when I travel. Sometimes floss doesn't do the job when I am on the road. It works just as well as my stationary waterpik at home.

    The battery does require some consistent charging. But in terms of power to knock out food items from the teeth, it's doing the job so far.
