The CKL-822UA appears to work as advertised, apart from a broken pin on one of the VGA-A cables. This kills the whole KVM setup as I can't use a second monitor or KBM on one of my devices. I'm leaving one star until I have a replacement cable. Edit: Support was quick and easy to get a replacement cable. Rating update.
