So far works great
I have only used the water flosser once.  It was able to get some stubborn pecan pieces from between my teeth that I have been fighting days to remove with floss and brushing.  My mouth is very small and teeth are tightly spaced together, and I was able to get to all of my teeth without any problems.<br /><br />The one thing I don't like is where the hole is to fill and drain the water.  It is located at the base of the unit and is difficult to drain completely.  Otherwise, great product and I would recommend it!
