I have 3 official porpers, one original joe porper, one dnd 1st ed porper and another of these I got free from a DnD lecture a few years ago, they were just giving them away so why not hey. My main problem is the scratching up of the box and it happens for all my decks, maybe if you got one from 'E' then they would be better for keeping the box in good shape as sinsandman has said. If you don't want one of those what I do is put the deck/cards I want to go into the porper into an old tuck case thats already beat up and then leave them in the porper for a while until it does it's magic. That way you get to fix your cards and you wont scratch up your nice tuck boxes.
