I just got the diffuser; but I am not at all happy because DIMENSIONS ARE FALSE (100 mm X 120 mm), while the site is marked (Kaavie - Softbox - Flash Diffuser Softbox Universal of Opteka for flash Screen Size diffuser: 200MM X 140MM). I picked this Article precisely to its dimensions. So mistrust believing all that is written, unless it is a confusion with a similar item, so a reference error, to do with amazon.
