It's OK. A little overpriced, perhaps. It is a quick and easy way of getting reasonably "shadowless" flash lighting. You'll have to boost the output by maybe 2/3 stop. I'm considering trying the "clear" version. Ocassionally, the "cloud" is a little too warm/soft.
the sto-fen omni bounce that i have for my 420 work better and gives mmore consistent results. light loss was a major factor. the 'chrome dome was really dissappointing, the 'kicker' didn't do anything.
A convenient way to get nice lighting in a fluid environment. Too bad the new mounting base became available two weeks after I purchased.
