I was looking for something as close to authentic NES controllers as possible for my RetroPie setup and these are spot on. The size, button placement, and response time is exactly how I remember as a kid. The only complaint that I have is that they are so lightweight they feel almost cheap, especially compared to the weighted SNES controllers. But don't get me wrong, they certainly don't perform like cheap controllers. I'm planning on taking one apart though and adding a little weight to it on the inside; kind of like Dr. Dre does with those vastly overpriced headphones.
