i just got this one for christmas. a couple things i like...The PSU, its 5v 3a so there is plenty of power. Also it has one of those button switches on it so you dont have to unplug it EVERY TIME to cut the power. Also, the case. It has pros and cons but i feel the pros outweigh the cons by enough to be happy with it. Its weird bc its 10 layers of thin plastic that are screwed together. But there is room for the fan, which is included, and over heating still has not been a worry. I know you dont need controllers but the ones included are not bad for being some weird off brand remake. If you are used to SNES they feel weird at first bc they are not quite the same dimensions. I have an SNES collection so im very familiar with the stock dimensions. Also, Retropi comes pre installed with Emulation Station which has TONS of options. Also KODI and Pixel were pre-installed as well...If you are interested I can link you to a YT video where you literally run 2 lines of code to add netflix (natively) to pixel!
i feel like this has everything i could ask for and at the price, would blow either of the Nintendo brand classics out of the water. I would give it a 7 out of 10. Just my $.02 i have no affiliation with these guys.
