I have one of those in my "Why did I buy that" box. It's fine as a shade and I even made a 72mm ring for it....but after a while the flags got loose and would fall off.
Kinda embarrassing when people would chase you down and say "Pardon me but you lost your flag".
I broke this in with the GH2 in Antarctic, did what it does. Fast, durable and immune to sea water.
