The box is set up quickly, it takes a little sporty from the unexpectedly small pouch. The carabiner of the interim diffuser are a bit small, pokes the Velcro of the outer diffuser - if you want to find fault, you can start here. The entire structure takes (tripod, flash, box with diffusers) takes about 5 min.
Now the decisive:
The box swallows with diffuser only about a stop! For the Yongnuo YN560 III I recommend setting the zoom reflector to 24 mm without Streuscheube.
The light meets expectations 100%. The brightness distribution over the surface is very uniform (see photo). The light is softer than the Firefly II, which acts more like a beauty dish.
Who travels a lot with the Box has found a very good solution. For outdoor use, I would like to limit that I still have too little experience in clamping of speaker on the flash bracket.
What I also get a good nose full of Chinese flavors. I hope that the more improved.
4.5 stars from me because the product at a great price conjures marvelous light and is highly mobile. 0.5 deduction for smell, and the posh end Velcro.
Oh - Who has never merged a Foldable Background, which should strive to Youtube before the first folding :-)
