I've used some old "square" HDMI RCA boxes and they work but you can get a bad one. I keep spares just in case and always check them when they arrive. This is a different form and possibly a newer and possibly improved version. I can't say for sure, but it worked right out of the box and seems a little better than older versions. Only time and continued use will tell.
