I have two of these units. This does not have to be marked "Skymaster" but are identical! My two "HDMI switch box 'Black', 4-IN / 1-OUT" cost around 15 and are now more than 15 months without defects in daily operation. I have recommended this device even more known and previously received any negative feedback. It's very annoying if you like - Peter (Pforzheim) - caught a "Monday device", but in my experience this distribution has therefore not only deserves a star! Therefore, 5 stars from me and I would buy it to me again !!!!!
