I know Oehlbachkabel as very valuable high products. This cable has not let me down from the quality. Unfortunately, it keeps still not what it promises. 20m is on the role, in reality, there are unfortunately only 18,8m. It is missing more than 1m Cable! This circumstance I find from Oehlbach but a little disappointing. I was going to cut me out of the cable 5m 4x, now I have 3x 5m and 3.8m once.
