I remember seeing something like this on QVC a few years ago as a TSV, at a higher price. I couldn't afford it then, so missed out.I remembered about the sender this year, done a search and found Amazon had it for the best price.
Installing - out the box and in use in 5 mins, seriously.
Quality - the signal only has to travel 4 metres from one corner of my room to the other, so the quality is fantastic. But it does depent on the quality of the Material. It does have 4 channels to select in case of interference from a neighbour with something simular, I found interference on channel 3.
I would highly recommend this item if you are fed up watching DVD's on a small monitor and don't have a TV out, don't want to bother with cables, or is simply not a person who wants to open their PC up.
