Query: Worked some of the times, for a while

I bought this when it first became available, as it was one of the very few options available. I was using it to distribute my dish satellite receiver's hdmi output to 2 TV's. It never quite worked correctly; among other quirks, you had to turn it on *after* the receiver and TV's were on, and you sometimes had to power cycle it multiple times to get the TV's to "sync" up. I'd skip this and look for something else. I'm currently doing just that.
