I use a Canon 580EXII, a battery pack, the Phottix Varos shoe mount and a Pixxel radio-timer. When shoe mount, you can remove the flash bracket and plug it back at 90 °. Then the lightning is parallel to the shade structure and it extends deep into the box. Then you can enclose it with the laces wonderful. The flash and denFunkauslöser you have rotated through 180 ° plugging. This works fine. The whole assembly takes less than a minute with flash and battery pack. The softbox itself is to act like a normal screen. Only when folding you have to let the air escape, but that is also very quick.
How good is the material I can not judge. This will only show the permanent use. Anyway it is a great value for money together with the transport envelope. One can not go wrong. Although I have even a Firefly (of course, is an entirely different quality) but I'm going to buy myself another screen.
The only shortcoming is that protrudes far beyond the shoe mount the long pole. But is due to the screen resolution is not possible otherwise. Is just a compromise. I just put a tennis ball on top of the pole, so that you constitute a danger.
