I had a Ripcurl E-Bomb from 2013 or 14, and that thing looked like it was uses 20 years, after just 6 months. Seams toring apart, lining peeling off, knees splitting open, discoloration. Fit wasn't that great either tbh, forearms and lower legs waaay to small.
Got a Ion Onyx after that, and although the suit itself was fine, it had problems with the knees splitting open right next to the protectionpatches (ironic), and seams tearing apart on the inside mostly on the back. Got a warranty replacement, same problems again withing 6 months. Got a warranty again, but a backzip (Strike I think) and again, same problems.
Now I have an Ion Onyx Amp, got a pretty good deal and the fitment for me is excellent, and it's way better than the older regular Onyx. The seams are protected on the inside so no problems there, and they have finally changed the kneepads, so no more tearing there. But I have it for 9 month now, so can't comment too much yet.
Not sure if I'll stick with the brand. Plenty other good stuff available. Billabong, ONeil, XCell, C-Skins. Patagonia, Matuse etc looks good too, but very expensive and I'm not sure how they hold up when you get dragged in the sand sometimes. I keep away from Mystic, Prolimit, Manera etc, although Ion is in the same league.
