Exactly what I was looking for [SEP] I needed an in-shower water flosser, which is harder to find then you would think.  This works very well with multiple head attachments included to help you use it as you need.  The battery life so far has lasted weeks on a full charge, although this does lead into the one drawback with this model.  It comes with a USB cord, no power adapter.  This is very annoying as most people don't have a USB attachment in their bathroom, so charging this can be frustrating.
