I received my new Mutant HD51 receiver yesterday, and I must say I love it as it is quick and responsive to any button pressed on the remote.
It has been switched on for almost 48 hours now and doesn't even get warm, unlike another receiver I had last week which got very warm to hot after a short while before it became unresponsive.
I have been trying out a few skins, other than the default one, and the xbmx confluence has my vote, and looks great, but each to their own I guess.
All in all I am delighted with the Mutant HD51, and I'd like to thank the people who suggested it to me.
