I've had several different Waterpik products and this is great! My dentist said since I started using it years ago it has immensely helped my teeth and gums.
This unit is so well thought out. I like the storage compartment for the "tools". The water compartment is easy to remove and fill. Also, I like the placement of the control button because it does not interfere with your grip on the handle. There is so much is such a small footprint. My teeth have never felt so clean!
