Yes indeed, they simply reload branded cassettes with cheap and nasty stuff, there was a big hooha a few years ago about grey imports of film and a lot of it was reloaded stuff, it's been going on for years especially in single use cameras, open up to take the film out and there it sits taped up to the eyeballs with any manner of sticky bits and bobs, also in the past we've had films that were attached to the spool by masking tape, staples, black insulating tape etc., which is not evident until it tries to travel through the film processor at the tail end of the film.............. or in some cases, not attached at all
