Query: Very Handy If You Can't Bounce Off Ceiling

I was looking for some sort of softener for myNikon SB-400 AF Speedlight Flash for Nikon Digital SLR Camerasso I could take portraits or macro shots outside. The sb-400 flash is great but can be a little harsh if you dont have a ceiling or wall to bounce it off of.This diffuser works fairly well and is very easy to carry around. I've made another diffuser out of a sheet of paper which works a little better for portraits, but is flimsy and not very portable. I'm sure I'll always care this around as it's very small and doesn't seem like it could break.Great item to have in your bag.
