I bought a refill on the site, nothing to say on the sale and delivery, on the other hand on the product I am disappointed. This is not my first cartridge but this a fault that I can not correct: this is only the folds! I'm undo and redo the installation of two pre-bonded films, but I only spoil the movie. At that price I think it should never pose this problem. Otherwise it is a good product ... when there is no such default
