I bought this flash diffuser because I do not have the money right now to buy an external flash. Of course, it will never replace a good old flash facing the ceiling, but it is still quite effective. The white filter softens fine. I have not tried the orange and blue filters, I do not see the point. I am surprised to read here and there to read that the object is not solid, nor practical. Mine was easy to install. must force a little, but suddenly the broadcaster does not fall itself when it arises somewhere the camera. There is absolutely no gene opening and closing of the flash. I have made it 4 stars because, in my opinion, the orange and blue broadcasters are useless. We could do without the hassle of 2 additional broadcasters.
