Rockboard Flat Patch Cable Black 20 cm

A flat cable with seriously flat connectors, all basically cast in one piece, seems like the obvious answer to ever-increasingly camped pedalboards such as mine. Add to that the promise of German craftsmanship and I hoped for a great solution.
Sorry to say, out of a batch of half a dozen or so, at least one was faulty, malfunctioning from the start. At first, I thought I might be mistaken about this, but then I read several German-language reviews where users had experienced the same thing. It seems like Rockboard needs to up its quality control quite considerably.
I'm concerned now that the others will give up on me too, in the middle of a gig. That isn't something that makes me enthusiastic about buying Rockboard cables again.
