I have been reasonably happy with the Rose KVM switch. The PS2 cable ends have caused me many difficulties in using it on my computer bank. Especially with those that did not have PS2 ports on the computer. I found many of the so called adapters didn't really adapt. I also found they were not readily available. Others tended to be quite expensive. I had to upgrade another computer to Windows 7 even though I do not use it for internet communication. This apparently a good product but didn't work well for me. I replaced a $20-$30 KVM switch with this system in an effort to get a more reliable set up. I'm not sure that I have accomplished this.
