Stuff like SS316 double and single ender clips that I've bought have been outstanding. Way cheaper than branded stuff, and not one has failed me, or rusted. Some I've had for a few years even. They're probably from the same factories that make the branded ones.
I've been using a wing from KeepDiving over the Australian summer, and it's held up exceptionally well. Both physically (threads, dump valves, inflator hose and valve - all unchanged), and visually (no discolouration from the brutal Australian sun/UV). I might make a thorough review here sometime. Friends like
@Tassie_Rohan keep giving me a hard time over the green camouflage pattern, but other than stylistic choices, I have no complaints.
I've had some weight pockets for over a year now too, and they look as good as new. Torches can be hit and miss. Basically most small accessories can be fine. I just stay away (for now) from anything critical like regulators or dive computers.
The only recent purchase I can remember being bad are silicone mouthpieces. They're absolute trash, rough edges and rather small. Some people complain in the reviews about masks being too small too. I haven't bought a mask there, so I can't review further. Sizes for anything you wear (swimmers, wetsuits, gloves, masks, boots, etc.) can all be a huge mess, they're not consistent.
