Bests & Worsts Reviews from Amazon

Reviews for this item were pretty good. All I want to do is feed my one HDMI Sony Wega tv with content from the cable box and content from my blu ray player. Set up the switch easily. Can't mess it up. Turned on the cable box and all I got was flash, flash, flash. I checked all the HDMI cables individual directly fed into the tv and they all work. Can only blame tbe switch. Bummer. I'm told the power will correct the flashing problem. Why I need it and most don't is a mystery to me. But there is a spot to use the power cord to eliminate the flashing that I am getting. Power cord did not help. LATEST April 10---I've bought another exactly same product. It works fine. The first one was a dud and I threw it in the garbage LATEST LATEST June 1---Power Light is on, but does not transmit. Item worked for two months and has now died.
