Rated 4 out of 5 by from I think I love it I love the cleaning and the removal of food debris. Your teeth feel great afterward. There is a learning curve to avoid giving yourself a bath, but that's true with anything. I will never again be without a WaterPik.

Rated 5 out of 5 by from The ability to control the water pressure The ability to regulate the pressure is very critical and the reason I upgraded to this model. I am at an age if I loose any more teeth I must go to a plate.,

Rated 5 out of 5 by from The Hype and Advertising are TRUE! I absolutely hate using string floss and went to the Dentist twice a year for cleaning. They were my "floss". We saw the GETWATERPIK.com ad and My wife and I bought two of these; one for our home and one for our Gulf Shores Condo. We also have a traveling unit (battery operated). The 'sale' price was great. Last, we bought extra "pics" but have been using only the regular pic. Each day we have filled the tank and used the "4" level for intensity. I even mixed "MINT" mouthwash with the water and then put in a little extra water at the end. We are truly amazed how effective the Waterpik is in getting all the interstitial areas clean between our teeth and how our teeth FEEL afterward. You can feel the water jetting through the gaps in the teeth. My wife makes all kinds of "Beef Jerky" in a dehydrator and you will immediately feel and SEE the difference (in the sink) when you use the Waterpik. We have NO reservations in recommending this model to any customer.
