Excellent construction, I have had it for 1.5 years and it works fine! It has all the cables, so you don't need to buy extra.

For office use / programming, it works as it should. Currently tested only with 2 PCs In and 1 screen Out, no problem with HD screen resolution or connected USB devices except for the following: in order for the KVM's internal shortcuts to work, I read somewhere that you definitely need up to USB2, in my case indeed they don't work with a USB3 keyboard+mouse receiver, but they work with a wired USB2. Also, unconfirmed information, a USB2 hub may be needed for the shortcuts to work with USB3 keyboards.
