I bought this after I got a full set of braces on my teeth. It's wonderful at getting all those spots that a brush and floss have trouble reaching. My mouth feels extra clean. Easy to use. Came with 6 different cleaning tips!
I am happy to have a new machine. The plastic on the old one faded over the years. I am really disappointed with how noisey the motor is on the new one. I have a friend who felt the same way. He took the motor out of his old waterpik and put it in the new one. Unfortunately, I already threw my old waterpik away.
