Does what it is supposed to
Bought this as my dentist said it would help with my cleaning , plack and gums. I have been using it for about 2 months. I use it after I brush. I found that it washes out a lot that the brush does not get. You have to let the water drain from your mouth as you use the pick. A little messy but just lean over the sink. The pick and your hand will get wet. Better than holding it in your mouth. I find one one fill of the reservoir is all you need for top and bottom. The negative is the batterie. It is not keeping a charge. I have to plug it in after each use. At first I would get about 2 weeks, 2 x a day  before charging. Now I have too charge it after each use or it shuts down after you turn it back on. I would like to get a replacement. Doesn't seem to be getting any better
