Hello Zilla, I bought two of these USB extension cables. They work fine as extension cables.
However, my USB extension cables do not have an automatic unwind or rewind function. You have to adjust the length or roll up yourself. I hope I have provided some clarification.
Yes, this is basically possible. At most, there is a minimal delay, the longer the cable. So for a pro gamer it's rather a bad solution, but otherwise I would say that you wouldn't notice any delay at 3m.
I have even connected wireless receivers to USB extensions because the PC is at the other end of the room, for example, and I still wanted to be "wireless" and the wireless distance was not quite sufficient. Also mouse and keyboard connected to 1 receiver on 1 USB extension cable without any problems. Hope this helps.
