Nah, theLloyds loader are mechanically the simplest. They simply have a dark chamber for the bulk roll, a felt covered slit for the film cassette to sit in, and a door that closes over the cassette. There is no intervening mechanics, so there is very little to go wrong. I have three of them, and one issue I have noticed, though I don’t think this would cause the OPs issue, is since my 3 have been made at different times, the crank (which is not permanently fixed in place) on one is too tight for another, so if I accidentally mix up which crank to use, it can be too tight, and be very difficult to load the film.
