I bought this diffuser, because my other has dropped by Gummibandf at the slightest vibration. Since it was called the fit, I ordered him. I suggest that you first plugged the device to flash and then all the DSA can be a while, so that the diffuser can stretch a bit - since the very beginning I had problems to get the part euf my EX430II. Meanwhile this has improved - I have the edges cut away inside something (is indeed relatively easy in the soft material). The function of the diffuser convinced exactly as in my other. This small, square diffusers I probably will not soon stop using. As the diffuser is made of hard plastic, but from a "gummy" material, nothing happens if you take carelessly throws it into the backpack - that was not the case with my old device. All in all I can do part of the price only know! The delivery term was also positive.
