I bought this because at work I use 2 different computers (each with their own monitors) that are not connected to the same network (no software KVM option) and I am very tired of running 2 Use keyboards and 2 mice. It worked great, not a single problem the whole week I've owned it. Switching between computer 1 and 2 takes about a second, but that's about it. I am very happy with it. I want the LEDs on the top to be visible at an angle so I can lay the box flat, but that's my only minor issue.
