I ordered this a few weeks ago from EBay for just under £9 and a few people asked me to post some details when it turns up, so here goes..
It comes in a small, flat, triangular bag that takes up no space at all and the unit itself seems pretty solid and well put together. The internal velcro straps (see below) are at a rather strange angle, but overall I'm surprised how nicely made it is. When you take it out of the bag it's not quite spring loaded, but a quick poke and it pops open to a roughly square shape, and when it's squashed a couple of times it stays in a pretty stable shape that's as close to a square as I care about.
The flash goes through an elasticated hole at the back, which is nice and snug on the 550EX I tested it with. I think it will be easily snug enough on a smaller headed flash like a 580, but if there is any movement there's two velcro straps you can tighten around the back of the flash head to keep it in position. The insides are a silver reflective material:
The velcro straps in the corners are for attaching the internal panel/baffle/diffuser/whatever-you-want-to-call-it by hooking it onto the velcro and pushing it down to flatten it:
Then the larger panel attached to the front edge velcro and you're good to go:
I took a few shots in a mirror with the flash on 1/128 and large apertures, just to get a feel for how even the light is - bearing in mind I hadn't done a particularly careful job putting it together, and the flash was at 24mm but without the wide angle card flipped down, the results weren't too bad. At F22, ignoring the creases which look a bit odd, there's an definite hotspot where the flash head is, but it's not too bad and everywhere is getting lit. Once you get up to F8 it's looking pretty even:
I'll post some test shots in the next post..
