My favorite model after years of various WaterPik products. Size is more compact, fits on sink vanity better, the piks fit into the lid, front storage of wand is more convenient.
I wanted to know, I never could get my hands on one. Now that I have one it's the best thing of ever use that helps get food and other things out from between my teeth without causing my gums to bleed. After use the WaterPik and then move into go get floss and floss after that. You can use a small Amount of mouthwash with it although make sure you clean your system out when doing so.
