Review on TNP 16-Port USB 2.0 KVM Switch with Manual Selector, Rack Mount Metal Box Adapter and 16 VGA USB KVM Cables for Computer PC Laptop Notebook Server Monitor, Keyboard, Mouse - Black by James Mcphearson

Others have mentioned this before so I'm not adding anything new here. It works exactly as you would expect. It features 4 USB inputs (2 front, 2 rear), optional separate push button controls that can be mounted elsewhere, and includes everything except mounting screws. Excellent value for money and quality. But there are two obvious things that need changing: 1) The included cables are short, only reaching about 2/3 the full height of the rack and hanging down. When you factor in something taking up the entire depth installed just above or below that KVM, you're really only getting half a rack at best. So I would include longer cables, maybe 12 or 15 feet. 2) The choice of LEDs must be different; make it green, white, blue, whatever. just not red. This happens in a server rack where people panic when they see red. Aside from those two issues, it's great.
