I reused the quick link that came with my SRAM 1110 & 1130 chain a few times (on same chain only) but couldn't reuse the one that came on my Red chain. I just started waxing my chains, one chain per week (4x1110 & a 1130). Three cycles so far so that al least four reuse for each chain (plus one for stripping the chain and one of quick link was reused once before). Technically it's 8 times since I reconnect the link after removing from the bike and do my rewaxing in batches with the link attached so I don't lose them. It's my indoors setup and no problems so far.
