Had one of the hand held types was good but takes lot of getting used too. It broke very quickly.

The larger units make so much noise when they pump.

Think you are better off with trying different types of floss...some i really hate and one i love. I also like the wooden sticks...think they are made by Jordan and i think you can really cleannyour teeth well with them- even better than floss.

I would not waste my money again on a watrr flosser...too much water spray and the pump makes way too much noise..will wake everyone
