I bought two of these cartridges and both were defective in the same way. The first few photos didn't appear as they should. I had to open the camera, expose the entire film to the light and, with some effort, pull it out. Of course, the rest of the film is useless. Hmm, maybe just bad, I'll try again. The same thing happened. Plain white frames worked well! This is my first review of anything but I had a very very bad experience. I saved both for memorable events and was quickly let down. Maybe a bad production batch but damn because they are so expensive you think they get better quality control. The first one I sent back as a replacement I'll pick up tomorrow, so maybe I'll do a sequel. TL;DR this movie sucks. Update: The replacement came and it worked perfectly. I will add a star. I don't think 1 out of 3 is bad.
