EBS Solder-Free Flat Patch Kit-10

I have a dozen of pedals and they were connected to each other by chinese cheap patch cables until today. After a couple of hours of work, I finally changed all the cables with these supposedly high quality ones. The result was, simply, silence. I started checking each and every cable and I realised that one of the two kits simply doesn't work (maybe a defective cable, I don't know). I spent two more hours to understand that it was not going to work and then I reconnected my former patch cables. Besides the defective kit, the whole stuff is overly pricy w.r.t. to what it offers. 3m of cable with a few connectors without the possibility of buying more connectors without the cable. The patch cables are fragile and steal a lot of signal. Terrible
