I had my doubts about what it could do and how well it could do it. I love this KVM switch. All data is routed between my two computers via a monitor, keyboard, wireless mouse and set of speakers. I just hit the NumLock key twice to switch computers. It takes about 2 seconds to toggle, and I'm fine with that. However, printers are not redirected. So my two printers are connected to one of my computers and then another computer accesses the same two printers over my network (just for setup). Once that's set up, double-pressing the NumLock key toggles everything back and forth. The kit includes all the extra cables you need. (How it works is pretty awesome.)
