I have a Recesky and can confirm that it is a fun build!
You get a few fowl language moments, especially when putting a retention clip on one of the spools only to have it pop out when you try and assemble the thing.
You will need a long screwdriver for securing the sides.
The viewfinder is just junk as it is so you will need a bit of vellum/rosco diffusion material/polyester drafting material to make it usable.
I haven't put enough stuff through it to judge but I really enjoyed the build, including those moments that need some improvisation.
Too bad there are so few kit cameras like that out there.
