Title: Waterpik is wonderful
Review: My husband's dentist recommended he use the Waterpik to prevent potential gum disease, so I gave it to him for Christmas. We both use the machine, and feel that it is doing a very good job of cleaning where no toothbrush has gone before. It is easy to use and maintain. We think this product is well worth the money.
