I've purchased several of these (pro snake mult's of various lengths) over the last few years for use on stage as a sound provider. So far they have been very reliable (only issue I've had is a loose crimp on a connector, as they are push fit XLR's a quick re-seating sorted it there and then), cable is good quality and coils well. Seem to be durable (no dead cores as yet). The Amphenol connectors are good quality alternative to Neutrik.
Very good value for money multi (and a world ahead of the cheap 'ssnake', that are rubbish these been the 'Pro ssnake' which are very good!).
The only bad point I can think of, is not enough room on the stage box end to put a strip of tape to mark up (could do with the panels punching with a little more room in between connectors for a strip of PVC tape).
Great value!
