Saw this a few days ago. It's definitely a good thing to have some real competition for the retron 5.
I love the hu card support, and was very disappointed by the lack of it on the retron, but, I don't see me replacing the retron for one, unless it does other things significantly better. The controllers already look better than the generic retron ones, but They aren't wireless, and I can plug standard snes pads into my retron.
