My wife purchased this a month or two ago because we have been getting extensive and expensive dental work. Works wonderfully...love the fact that you can use mouthwash/water combined in the unit. Does a great job!!!
love the water pik. teaspoons of bleach in a full tank of water and my teeth feel like they have just been cleaned. Only thing I would like is a larger tank, when set at 6 or above you run out of water too quickly.
