Used to switch keyboard and mouse between iMac and Thinkpad Win10 PC. And it works as advertised. Each system recognizes devices within seconds, if not faster. Yes, it has 4 ports and I may have paid too much to only use 2 of them, but I think something will happen if I need an extra one. And if something goes wrong with a port or 2, I have a spare for durability. I bought a cheaper single port product from another vendor but it didn't work with win10 at all. I think you get what you pay for (and now I can use my mouse between the two systems, so all the better).
