I work for a professional sound company, and we've purchased a lot of these for use with Behringer X32-Rack mixers and S16 stage boxes. Behringer used some sort of knockoff ethercon connector on the x32 product line, so actual ethercon connectors tend to get stuck. As such, we've started using these cables for short jumpers between units. They're sturdy enough that they hold up to frequent re-patching, but don't have the issue of getting stuck. I haven't tried any lengths other than 3' but if they're all similar I'm sure they'd be fine. The cable is flexible but not too flexible, so if you need a long run or are going to be frequently coiling and uncoiling, I'd probably look for something else.
PROS: Clips don't seem to break off easily.
Haven't worn any out as of yet.
CONS: Not very flexible, better for semi-permanent use.
