Title: Leaves teeth feeling clean
Review: This is my first Waterpik and I am not disappointed. It does a great job of cleaning between my teeth and below my gum line. I have only been using it for a few weeks and have already seen a big difference in my gum health. My only complaint is that the button on the handpeice that stops waterflow tends to stick and you have to turn the machine off before it will free up. Minor annoyance considering the payoff when using it.
