I use this to connect my Presonus RML32 mixer/stageblock to my CS18 controller. Very good quality and works without any problems. I also have one of 30 meters, one of 20 meters and one of 10 meters, so I have something for every situation. They are a bit rigid in the beginning but that improves after a few unrolls. I mounted these on a Schill GT 310.RM cable drum, the others are on a Schill GT 230.RM (see also my review of these).
Highly recommended, especially for this price.
