Bh's policy on this is not worth it. not returnable, not eligable for expidited shipping, and its not as useful as it could be.� But seriously, this item is not cheap, and everything else in my order was expidited shipping, Except this?� And this is non returnable?� So you are just stuck with a slow to ship item, that works but is annoying.� To insert a diopter, you need to dissemble form the mattebox,� It holds diopters very well but its not a quick drop in, as the door does not open enough to be able to drop in. or pull out.
