I've been using a Waterpik for many years. It's easy to use and cleans between teeth more efficiently the dental floss. I add peroxide to the water tub 2-3 times a week to help control germs. This is not my first Waterpik and won't be my last.
I am very happy with the recent purchase my of the Waterpik Water/Flosser. After brushing I am always amazed by the volume of food that is removed durimg flossing my waterpik.
