Summary: When I lost the original one I got a couple off-brand replacements.. They didn't fit correctly, lost one tossed the other, didn't want to bother even using it my mistake. The SW-10H saves my having to use the built in one which can sve its wear-and-tear.
Pros: Great Fit, Great light dispersion, Handy, Saves built in defusser
Summary: Bought this to replace the original one that got lost. Perfect replacement. While it won't give you the same softness as a brolly or softbox, it does improve the light quality when compared to bare flash.
Pros: Easy to Use, Lightweight, Strong Construction
