Look at the individual parts well before you start to build up (a manual does not exist). A small tip: Set the position of the locking screw of the joint fixed in advance, so that afterwards not get the curved bars of softbox bem adjust the angle in the way. Once built, the heart pleased with the great price / performance ratio and immediately turns feeling a to have bought the right product. The on / off switch for the horizontal and vertical lying lamps are the pure joy and allow a quick comparison of different lighting options.
