I've had a pair for the last year or so... and have be happy with em... except for the weight and amount of space they take up in my bag. I haven't had any problems... but I've been careful not to twist or bend the cables too much near the connectors. I've read that can be a problem... if too much twisting occurs near the XLR's... the connections can break... but can be easily fixed as well. But if you can put some Neutik's on em... solid.
But like I've said... I've had em for about a year, and have had no problems! They are 20ft. long, heavy, and bulky though.... but fairly inexpensive as well... good cables for the price IMO. And you might be able to find em at your local pro-audio/sound shop... at least in my area I can.
I just picked up a set of Kind Kables... and holy shite do they lighten up my bag A LOT!!!
