Just got my oxycheq 30# wing last week and got several dives in this weekend with it. I'm very happy with the exception of one thing. There was a lot of talk about the oxycheq wing having both an outer shell and an inner bladder but it seems as though it does not or at least thats what I get seeing how thin the overall thickness of the wing is and that there seems to be no way to repair the inner bladder if there is indeed one. I got my wing from Chris at COVCI and was told that it has a three year warranty. I didn't recieve any warranty card or anything saying when I bought it from COVCI. The inflator hose was the perfect length and the wing has an extremely low profile which I really liked.
