Works well, by just plugging in and connecting up. You only need to load the mini disc ( for each PC) just to view the connection speed in my opinion. You may need longer RJ45 ethernet cables as I did, the ones included are 1m in length. Be aware make sure you plug them in directly to a power socket. If you connect via power extension leads the speed drops dramatically-around 64mb. I have not achieved 200mb by direct connection, it's around 140-150 mb. The two units take a time (a few mins) to handshake to achieve the fastest speed, but I find this exceptable. This works well with downloading videos/ BBC iplayer/viewing You Tube clips etc, with no clipping--nice & smooth. I almost gave it 4 stars instead of 5 just because I could not achieve 200mb, as advertised, but at the end of the day its what performance you achieve, and my setup is excellent.
