I bought this switcher with some trepidation after reading various reviews for other switchers which had implied, in general for all brands, that I would likely experience some signal degradation. I am happy to report that this is NOT the case. The switcher itself is much smaller than I had expected, and very lightweight. I have the unit switching my SKY HD and PS3, and in all honesty the switcher far exceeds my expectations. A clever device with NO signal degredation and smart auto switch function. The LED light to show which device is currently in use is very bright, but as it is Blue (I didnt want the living room to look like a red light district or the wife would have complained) and hidden behind the telly this caused no problems. Well done Duronics!
