I have to be fair and confirm they haved worked flawlessly. They sucessfully connect your pedals. Period.
I've had zero issues, everything works great. Still, I have to give it three stars. Despite the golden sockets the cables themselves are thin and feel flimsy, like they could break at any moment.
I haven't taken them to live situations yet, but I was sincerely expecting something a bit more professional, specially when I've also bought patch cables from other brands at a slightly lower price that work as great and at least look reliable.
