That is feels good and you get a cleaning that no other product comes close to. I have tried several other products and thought my teeth were clean. I would then use the waterpic and additional food particles would come out
Does its job. I was never a frequent flosser as my teeth are very tight. This is a great daily tool between flossing. Needs a rubber seal on lid to help prevent spills between sink and motor and a tighter closing cover for pik heads. Have not found a pattern to laying all the heads in the clamps.
