This Diffuser is a Must have Item for all around flash use! (My SB-800 came with one, so when I purchased, my Backup flash unit : a SB-600: I purchased the Diffuser- since I didn't want to be without one.)
Purchased at a discount as part of a speedlight kit. Even at that, this item is way too expensive for a small bit of injection molded plastic. Adorama should give these things away like ballpoint pens and/or keychains. It is one of the least expensive diffuser's out there and it does do what it is supposed to do but, come on.....[$] kit price. [$] if purchased separately. I don't get it. If this thing costs a dime ($0.10) to manufacture and package I would be surprised. Sorry Adorama, can't support you on this one.
