I bought this a few weeks ago and used it to mirror my Mac to two other displays. This works very well. The splitter is very compact, so it doesn't take up much space on my desk. It cools well as I haven't felt any heating on its surface during usage over the past few weeks. The image was transmitted simultaneously and both outputs are very well synchronized. I would advise you to prepare an additional HDMI as you need it to connect to a signal source.
