Not anything special, but it does the job of replacing the original Intuous cable. It's not quite the same design as the original one, seems marginally shorter and is actually a bit different from the picture - the end that plugs into the tablet itself is actually bizarrely long and makes it wobble about a bit when plugged in, but not enough to disconnect it while using it, and it fits in fine. I haven't used it for too long, yet, so I can't say anything about longevity, but I'll update to say if it dies or anything if I can.
There are probably longer and better-designed ones out there for a higher price, but I'd recommend this as a cheap replacement if your original Intuous cable gets lost or broken and you need something quickly.
