The Kathrein EXR 158 meets all expectations I had of him. It supplies all the televisions and computers in the house with eight digital television signals and is also considerably more energy efficient than the old 4-port switch. However, the reason for this review is its unusual robustness. I had to drop the device in the first time installation, unfortunately, more than 2 meters in height and except for a small dent on a digital input it has taken no damage. My compliments to the company Kathrein for their apparently quite high quality standard (wherever that device was built)
