Review on 2-In-4 USB 2.0 Switch Box - SGEYR Metal, One-Button Swapping & 2 Pack A To A Cable For Printer/Mouse/Scanner Sharing Between PCs by John Blanco

Great little switch! I mainly use it to switch my keyboard and mouse between my two PCs, along with a hub.I wanted to be able to mount it to the back of my desk and access it remotely, so I soldered a long speaker wire to a momentary switch to the switch inside the unit. It works perfectly, and I've mounted the remote switch to the underside of my desk near the front, like a panic button for switching PC access!
