Use in or out of the shower.
I have been using this water flosser for the last couple of weeks.  This was a great investment for my oral health.  I bring it in the shower since it is waterproof and I don't like having water drip down my arm at the sink.  This unit feels good in your hand and gives a good thorough cleaning with one tankful.  I like that there are three different settings and different tips.  I use the braces tip for my hard to reach back teeth because of the brush on it.  The tongue scraper tip took a little getting use to but my mouth does feel much fresher after I use it.
