I went to Best Buy and Radio Shack and couldn't find anyone who knew the product. I placed a 50" TV at the gym 80 feet from my desktop computer. First I tried to connect a splitter and the picture was darker and worse. After purchasing and receiving this 4-port (amplifier) box I was very pleased with the results. The picture on the TV was just as good as it was on my 23" monitor. I also ran to the TV in the living room. All good and I would buy it again. It arrived early too. EXCELLENT work and product.
