Reviews say there are repeat games (typical standard for bootleg) but people seem to like it. A little disappointing that it uses AV cables but not too surprising. For the price, that's decent. However, if you're looking for a good alternative to the nes classic, I would suggest getting a Raspberry Pi and a few USB controllers. They're easy to program since you just pretty much dump programs required to an SD card.
I know two people who ordered this crap. Both had controller problems. The GUI is terrible. Get a raspberry pi and some USB controllers. A few more bucks and you can have all the NES, snes, genesis, arcade, Atari, etc.
I actually own it. It's not that bad. It does have quite a few good classic Nintendo games on it. It has a lot of homebrew and hacks to but it does repeat games. I bought it for my collection. It's not bad for the price
