Hard to criticize given the price! It works well. However, since it is powered by your computer via an HDMI cable, the USB ports are not powered. So when your computers go to sleep or hibernate, you can't wake them up with a USB mouse or keyboard. It's not a problem for me, I just press the power button to wake it up. I would have liked the keyboard shortcut to switch between computers, but I knew it didn't have that feature when I bought it. Also pay attention to the low price and the good ratings. If I don't win the lottery I will definitely buy this again if I need another one.
