I've been using this water flosser for years. I tried several others but none of them were powerful enough to get everything out from between my teeth. My teeth and gums are much healthier and my dentist is happy with the results. This new version has an extra water tank and that is a wonderful bonus!
Have been a user for several years. Same good design and usefulness but with much more power. Have not used the XL water tank yet.
By far it’s the best one yet !
