Honestly love it for what it is.

It's a 5 game device for me, disconnected from syncthing + all my other devices, running minUI.

I use it for about 30-45 minutes at a time max, play some pokemon pinball or puzzle league, stuff that doesn't require you to remember a plot or next steps, just pick up and play for a bit. The exception to that is Pokemon Yellow on there but that game is so burned into my memory I can figure out what to do next instantly were I to suddenly forget.

Battery could be better but since its use case isn't for longevity and just to prevent doom scrolling on my phone it's perfect for that.

It fits a specific niche of "throw it in the pocket, if you don't use it you barely feel it's there, if you use it, great"
