When the thing works it's great, but not always. For example, if you connect a DVD player to it, it works fine, but if you unplug the DVD player and then connect a computer, the computer's signal will not appear on the screen. If you fiddle with it for a while, a computer will suddenly appear on the screen. I would probably buy it again if I could turn back time, but for the price there aren't many other options.
