Just got mine and it is good
The screen is nice
the controllers are good and plug into usb-c ports on the side of the unit.
It comes with an mini hdmi cable and to bad that they had to do this because they they have space for a full size.
It also comes with a usb-c cable for power but not the power adaptor.
The speakers in it are the worst it has a headphone jack luckily.
To note: there is no internal battery; you have to plug it in to external power. A USB battery pack will work, too.
Lots of games, fun stuff. Metal Slug is just as impossible as it was 25 years ago.
Also to note: the controllers work in Windows 10, to my tests. I used a USB-C to USB-A adapter. I have been playing Cuphead on PC with the white one. According to reviews, standard USB game controllers won’t work on this console, however.
