I used to use it a lot - not as an end product, but for checking exposure, etc
the only reason I stopped was I stopped shooting 4x5.. but I kept right on with the pack film for my RB or hassy (yes..I know that wasn't p/n)
but I really don't care if it's PN or not.. the N was just a bonus for me
but 6 bucks to test exposure? meh
