Not OP, but I have this handheld and it's pretty great. I think its the 2nd best retro handheld in a package similar to the OG Gameboy, but is much easier/cheaper to find than the miyoo mini. There are a few little things I dislike about it, mostly relating to the software. GarlicOS improves it but still has a few weird quirks.

I'm also not OP but I have one of these. Also using GarlicOS. Took a bit of tweaking the get things set up, but loving it. I'd definitely recommend, but you may need to fiddle to get it working exactly right. Struggles with some PS1 titles, but otherwise excellent.

I just got the 353V a week ago. Great device, same form factor as OP with two analog sticks at the bottom for games that need them. Think I might pick up a few more so the kids will stop stealing mine.
