I bought it to expand my audio interface with an additional 2 in/out and it works flawlessly. The quality feels good and both have held up without issues so far (I've had the first for almost a year, recently got a second one).
I can't decide if the length is awkward or just perfect:
On one hand it's on the short side, limiting were I can place my SPDIF device but long enough that I'm concerned it will be problematic to have it connect a rack unit in the slot above the interface (partially due to the stiffness of the cable).
On the other hand, it's kind of just the.. Well perfect length.
You can connect two devices mounted on two separate, side-by-side racks or have one placed pretty freely on a studio desk and connected to a rack mounted unit in the same desk.
All in all, I'd recommend it but wish they came in different lengths as well.
