It's the same console they have been selling for years, with nothing new except for the colors (it used to be gray and yellow, but now it's silver and blue, and the stickers are different).
I have one. It works well, but it's very light and probably uses a NOAC. I can't test it with many games because my cart adapter does not fit in unless I remove the plastic case, something I don't do very often. So I basically use it to play those yellow chinese multicarts which are always easy to find (although I haven't bought any in a while, specially after the PowerPak).
Mine came with a 64 games cart. There were some good games, such as Castlevania and Contra. There were many famous games, but I can't think of any others right now.
EDIT: This is the one I have:
