Has anyone ever tried using these?

Usb active extension cables

I'd like to know if they work as well as they say, I've read a few different places that you can use up to 80 feet of them together without any problems. But none of the sites selling them have any user ratings. I would like to know as I am relocating my computers to the basement since it is much cooler down there and the ps/2 cables I have don't work for the mice for 2 of the 3 computers. So I'm planning on running it usb if possible. I'm looking to go at least 16 feet if not more, my monitor cables are 25' and they are working just fine.

Also I'm planning on replacing my ps/2 based kvm switch with one of these, has anyone ever tried a switching usb hub? Does it cause any problems with frequent switching back and forth, especially with applications that need to stay in the foreground only (don't want windows constantly telling me I unplugged a device whenever I switch to the other computer)
