I bought one of THESE
a few months ago.
I gave kind of neutral but positive feedback on it, before I had really used it.
Well, now I have used it a bit. It's excellent quite frankly. It's cheaply made, but that hardly matters as it won't be wrestling bears or used in a hurricane. The diffuser in particular is brilliant. Just fold it down over the front of the flashgun and fire away. It's meant that I no longer get out one of the rather cumbersome mini soft boxes to get a similar, although not quite as effective, result.
Seriously, for less than £10 it's a steal.
