Could anyone enlighten me enough to get through a test to be sure it works? I can't even tell if I need to purchase a film holder or if it comes with one? Do you see any red flags, issues, concerns from your experience? Thanks so much for sharing your knowledge! Hopefully I'll win it and it will be E+++++ as stated!
