The rewind and back looks identical to my Wide and Slim, as does the 22mm lens (tiny front element/large rear element). No surprise as Reto is also selling that model too. I would think if one were very careful with winding on and rewinding that it could last for some time. As for price? Yeah, seems a bit steep but a Holga with a built-in flash is $59.99 at B&H so.....maybe not so bad after all.
By the way, the Reto Wide and Slim, which does not have a flash, is available for $29.99 and is even 'in stock', while the half frame Kodak is not.
But, on the other hand, they also have a 'Kodak' reloadable 35mm with a flash and 31mm single element plastic lens for $23.99, but it does not look near as nice as the H35.
