The lomography action sampler is a poorly made, highly marked up, piece of plastic junk. I've given other lomo products a lot of leeway given that we're not going for super-pure photographic imagery here, but this item is simply very poorly made and in my case, didn't even last the first roll of film.
The low-tech four shutter triggering system seems to be driven by a spring which resets when you wind the film on, which would be fine, if the entire mechanism had any type of quality control whatsoever. In my case, one or possibly two of the shutters get triggered then it whines to a pretty lame sounding halt... After then winding the film on, it will most likely try and trigger again, wasting another frame of film.
The photos on lomography's website for this product look great, but I wonder how many rolls of film you are expected to waste (and remember, you have to buy the film and also pay to develop it), before you get even 1 decent shot.
Utter junk, avoid!
