Water Flosser Professional Cordless Dental Oral Irrigator
I like it!  It took a little getting use to as I started on too strong of a water stream.  The reservoir seems a little small, but I just fill it twice.  Maybe once I get used to it I can finish before it runs out of water.  Also seems like the charge does not last that long.  Again once I get used to it, it maybe just fine.
