I wanted to move my AV stand from my living room to my office to free up shelf space and improve the look. I chose them based on the price and the generally positive reviews others have given them. I tested them with the video signal from my AV receiver to the projector on a 50 foot run of good quality solid Cat5e cable. The result was very disappointing. Contrast and brightness dropped off badly, and I had very bad ghosting on the edges of the subject. I tried a 1m Cat5e run to make sure it wasn't a cable and got the same results. I ended up returning them and spending the extra money on a couple of Intelix units and they work fine with the same cable.
