It sounds like it's not advancing the film properly, which could be you loading it wrong or could just be something wrong with the camera. Also, with a shutter speed of 1/100 and an aperture of f8 (according to Amazon, this is what it shoots at), you want bright light or fast film, like ISO 400. I think even with the built in flash, your subject would have to be close for it to expose properly. Also, if you decide to return it, maybe look into something else that was built for simplicity but has a little more reputation for consistent performance, like a Kodak Pony or the Bakelite 120 cameras as was previously suggested. Plus, these cameras look a lot cooler than the lomo cameras, in my opinion.
