Title: The best Waterpik!
Review: Simply put, this is a great Waterpik. The pressure control dial is accurate, and the reservoir tank is the perfect size. You have an ample amount of water to do a thorough job for your entire mouth. I use this in addition to flossing. Adding a mouthwash to the water is a good idea. I have owned mine now for a few years, and it still works just fine.
