I received two of these to work with different TVs at a trade show. They're the cheapest I've been able to find with an HDMI connection, and both worked flawlessly even when we worked non-stop for a week, 24 hours a day on a continuous cycle. They are also a good small size. The only thing you need is control as not all the buttons you need are on the player itself, but that wasn't a problem for me.
