TrustedReviews have looked at the Thermaltake Media LAB

The remote control itself can work as a mouse, and a virtual keyboard is included, but I found the controller had a bit of a mind of its own and I couldn't get much in the way of accuracy at all - but to be fair that's not really what it's designed for. It is also possible that my unit was faulty though, as it tended to want to float to the top of the screen. It worked best when inside the bundled software, where clicking up, down, left and right sufficed - just like in Media Center.
