Works very well. I use it to share a display on two computers. The transitions between displays appear to be fairly smooth. However, the arrangement of the cables on the desk is a bit awkward. With two cables coming out opposite each other, there's no good way to place it on the back edge of a table. In fact I have it on the side, the button is facing me. Aside from that little clumsiness, I'm very happy with how it works.
