I purchased this diffuser as a replacement to a StoFen I had before. I was very pleased to see that this diffuser is actually molded to the flash head of my 430EX, the fit is snug and its easy on, easy off. I also liked the fact that the material is a bit more transparent than my previous diffuser which may help with battery life as well as having the prism pattern on the front. This is a product that I can certainly recommend.
