Simple 4-port KVM, cables not included

After buying the trendnet 4-port KVM switch I suggested this KVM switch for my company to buy. While it is much more expensive because cable kits are not included, it is manufactured by a name I trust. I have not been able to figure out how to get hot-keys to work, and there is no online documentation, or any paper documentation that I can remember. It is a bit inconvenient that it doesn't have any connection for a USB mouse, but for the price I can't really complain. If you need a simple, reliable KVM switch, and you don't mind leaning over and pressing the button, this one is not too bad. I wouldn't recommend it for a server room.
