If the goods are really coming from Hong Kong, the delivery time was really great. On the versions of the lamps I can not find GS, TÜV or VDE mark. I wonder how the goods came through customs. Since I'm no electrician, I can not know exactly evaluate. Even the lamps are nowhere these characters. The structure of the screens is already puzzling if you've never had to do something. But as a photographer wants to indeed be creative. If you think a bit to get behind it as the screens are plugged together. The one to need a second person I can not confirm. However, the stand is built already thin and light, but it was on the whole photo session where I have portrayed it. The propeller blades of tripods are made of plastic. I do not care if they spin there at the hardware store thumbscrews fit. Unfortunately at the first photo session a lamp is broken and I had to order replacement. Can happen, would the supplier in Germany, the guarantee would be easier. Consider !! The price of this set is very low, but I've had enough and we have fun with it.
