Yes I've had 2 leak on me also, though it took a few months of use before it happened. I put up with it because it was so helpful. And because I used it so hard (2x a day, I never bothered to complain to the company) But after the 2nd one, I gave up and bought a real waterpik machine and the grossan adapter tip to use with. I'm much happier with that. National Allergy Supply sells the Grossan tips for the waterpik.
