I have yet to find replacement heads.  So this is just disposable?!?!
1st impression: It works. But in 3-4 months it's going to only be good as a water pick because iI just searched and they don't sell replacement brushes...<br /><br />After one month of use: Both mine and my wife's brush is working intermittently. The water pick pump keeps engaging and the brush doesn't.<br /><br />If you could see my face you would be looking at regret.
