The unit I have now for some time in use. The IR receiver is located at a distance of about three meters below flat on its feet. The TV is on a Lowboard in approx 35cm height. The unit and the two signal transmitters sit in Lowboard on the underside of the top boards in front of the equipment. Thus we see from outside anything except the IR receiver at the bottom of the TV. As both parts have the same color and goes away, the cable to the rear, it is almost invisible. The cable length is sufficient, in my view, so that the IR receiver can also be mounted further up above the TV. To function; I use a Logitech Harmony One to control all devices such as televisions, decoders, DVD etc. All devices can be operated without problems, the signals are passed properly to the device. I highly recommend this device, as long as you have the visual contact with the IR receiver all works as it should. Visual contact with Infrared yes but also Mindestvoraussetzug for the function. The maximum distance is with me about 4m, moreover, I can not try it.
Conclusion: Impeccable functioning product at a fair price. Recommendation.
