I bought this after getting very good results from a tiny 50cm sliver reflector I got as part of a kit. I'm rather regretting it now - this 33" silver reflector is to my mind too shiny, meaning that, instead of spreading the light from my flashes to create a soft effect (as the 50cm reflector did) the light is concentrated in a rather harsh way. The upshot is, the light from this 33" reflector doesn't really look very diffused... it's more like the results from a direct handheld flash with a bit of tracing paper over the head. You certainly can't use it for lighting anything bigger than a chessboard without getting hot-spots.
If you want that kind of effect, great, but if you want soft lighting, go for a white diffuser. I should have.
