The official position from the companies is don’t do it. That being said, I’ve reused Shimano and kmc 11 speed quick links/master links without a problem. Just make sure it’s properly locked into place and isn’t misshapen. As for sram, I’m not sure because I’ve never used sram chains. I’ve heard/read that their quick link option has a higher chance of deforming upon reuse. However, I do know people who have reused the sram links just fine. Officially though, yor reuse them at your own risk.
