Thank Goodness my old Waterpik quit working...
This water flosser does the trick and takes up barely any counter space. We purchased after the pump stopped working on our BULKY waterpik unit and at a much more reasonable price .  We've used it for a week and are very satisfied.  The water reservoir is just large enough to get a thorough cleaning in one fill-up, but is easy to refill if you want a longer cleaning.  We love that it came with four color-coded tips.  I  highly recommend!
