I've been using this for about 2 weeks now. I brushed my teeth and then looked into the mirror and surprisingly found a food particle between 2 teeth near the front. I used the pic and it was gone along with a few more particles. Works well.
I bought this for my daughter to use with her braces. There are lots of different attachments to use. The reservoir is a little small and I wish it held more water for longer cleaning time.
