The device complies largely my expectations. I have in my two PC's (once win8.1, once Win7Pro) but select before switching on the PC's desired PC on switch, otherwise the video card will not be activated. Is not bad, but you should know. two to three USB plug more would be great, because a scanner and a printer occupy the two existing. Now and then it happened to me that "lost" my win-wireless mouse when switching goes. That should, though rare, is not going to happen. Otherwise, all good, installation simplest.
