Bought 2, they gave dropouts with AES50(M32), after measuring with a Qualifier it didn't meet up to spec. Cut them down to 50M and they worked. I bought several of these cables in several lengths becase they have pro look but lot of them are not up to spec.
I still buy them, but cut them in pieces so I can ad a heatshrink for labeling and crimp my own connectors. I always measure, sometimes recrimping the connectors makes them up to spec.
I recommend thomann's purple CAT5E cables they are better but he connectors are not really nice.
