Hi - we have used the set in the water quite a few times now. My fiance' and I have been using ours for almost 2 years and they are still like new. Traveled to Thailand with them, Exuma, Mexico, a couple of cruises and a few other small trips and honestly, they have really held up extremely well. In terms of the mask leaking, we have never had any issues with that. We are quite pleased with them. Hope this helps!
