It's a pretty normal-crappy cable which does the job, but it costs a lot of money considering what it is, it should not cost more than 2 euros.
I used it to power a pedal from my TC Electronic Tuner. My main power comes from a Voodoo Lab power station a the cables are faaaar better, so that's what I'm comparing it to.
I hope it will last, since I have it on my pedalboard and it hardly moves. If it breaks or gives me problems I'll update my review.
