Property me the part ordered, inter alia, by the good reviews. So same time tried and I must say I was totally surprised at the beginning, because a concrete image degradation I could not tell. Certainly, what measurable but because I share a signal to me was clear anyway, and it's also for my application for this plan was completely ok. Only then came the end for the part. How correctly write quite a few users, although you can use both ports at the same time and you can eg Sat1 SD and look at the other Pro7, but as soon as I switch to an HD transmitter to the HD receiver, is at the other receiver off the signal. Ok, no problem I thought to myself, are so different transponders and then does not go flat. I could have get over. The biggest problem, however, is on a receiver from, the image is still running on another receiver, but once you switch to this, there is nothing more. No more message. If one switches the 2nd receiver again, the signal also on the 1st receiver is back. A changing cables at the terminals brought no change. I tried it with a HD receiver and a SD receiver, but unfortunately it does not. Perhaps there should be two equal Receiver? Otherwise, the idea is really good and the image can really be seen well.
