I used 7 of these for a project. I handed them out to 7 photographers of varying skill levels sand and gave them all the same assignment. Each camera is a bit different, not only in the sharpness of the plastic lens, but also in the shutter speed, I think. It's fine, though, it is a $15 disposable camera. You're likely to get 28 exposures. They are valuable as a terrific introduction to film photography in general and B&W in particular. As a way to spread the joy of film photography as a hobby, these things are top notch.
