The delivery took place on time. I had bought the soft boxes along with a pair Set Studioschirm lamps (separate review) and stated that it is the same stands. These are included in the price / performance ratio in order. The soft box itself is folded and stretched like an umbrella. Something "fiddly" designed with under the "clamping". For this purpose, has a central ring which is in the middle of the clamping bars, are pushed over the edge of the frame. It should be noted that this is already not verkanntet the "tension", otherwise the could possibly break the but "delicate" tension rods. The easiest way is for two. A (r) holds the version of / the other spanned by both hands the screen. After clamping and inserting the fluorescent lamp it came to testing. Plug in and turn on. The luminous efficiency is good, and the included diffuser "swallows" not too much light and does the job. The attachment takes place by means of Velcro. The box can be used purposefully. With the second box I had a little less luck. Plug in, turn on outside RCDs. After a few minutes troubleshooting I found this. The outer conductor of the lamp holder was bent inward, causing a short circuit. Probably by the turn they were now "soldered together". I complaining that the box has been replaced. Recommendation: check the contacts before the first "start-up"! All in all you get for the price of two soft boxes with a good price / performance ratio for mobile use
