Got this as a Christmas gift and I'm so happy I got it. Using floss was making my gums bleed a lot. This is much gentler and my mouth feels much cleaner.
Even after a long over due visit to the dentist and this product being recommended I spent much time on line reading reviews. Look no more !!! The water tank holds just enough to get a comfortable cleaning of uppers & lowers, inside & out. The variety of tips, dial selection and storage makes this unit convenient and easy to store when not in use. I HIGHLY recommend the water flosser to all, if you have never used a water flosser you will be amazed what your toothbrush leaves behind.
