Does'nt hold a candle to a countertop model
I had to refill 2 times per use.  I had a great deal of difficullty acsessing the backs of my teeth because if the flosser is tilted wrong the water won't pump.  Unless you absolutetly need a rechargeable, get a countertop model where every angle works & it's much easier to refill if needed.
