I bought a couple of these beauties to try my delay and reverb pedals through my amp's fx loop. They were one of the cheapest and best looking options, so I decided to give them a try.
They're surprisingly elegant - the angled jack takes very little room between pedals - and they look "expensive". The sound quality is also good, but I noticed quite a difference when I compared them to fender cables, which is understandable since these are half the price.
Overall, it wasn't a bad purchase. I quite preferred the sound of my reverb and delay pedals through the fx loop, but introducing another 12 meters of cable (2x 6m cables) in my guitar signal is a bit too much. For my specific case, it would be ideal to have a shorter version (1 - 3 meters) with angled jack in both ends. Nevertheless, these are still perfectly fine and good-looking cables that will surely be useful at some point.
