Yeah I'm not picking on the devise, I'm all about free enterprise and ingenuity but just want to let those less knowledgeable about lighting not to expect beauty dish quality light.
On this board a while back there was a DIY style beauty dish that was getting some talk. It essentially did the same thing. It was made from a large plastic potting bowl with a whole in the bottom. Some really liked the light from it, which is fine, it just doesn't replicate beauty dish lighting.
