Accordingly, my review is now written from beginners perspective, but that I should also belong to the target group of the sets.
The complete contents of the shipment including packaging has described in his review very detail Jachman Oliver, for that matter, I will not repeat everything but references to him. But now to the items.
The flash heads are quite large, much longer than for example the Mettle K300. Regard should be natural that this lightning 1/3 has more power, thus requires correspondingly larger capacitors. In addition, a fan is integrated and a radio receiver, both of course requires additional space in the housing. The fan works quietly, but audibly, fell in my tests but not adversely affect. In quiet environments, it may be disturbing, but you will probably build the rarest flashes for example at a wedding in the church ;-) the flash is controlled via a keypad on the back. The flash output can be adjusted in 30 steps, using the enclosed remote control. The less fine-grained modeling separately and only switch on the flash. When down rules of flash output, one should keep in mind that the flash now excess energy stored not like some other flash heads on a short flash degrades. The first trigger after the sale takes place even with the previous rules, higher power, only after that the flash works weaker. The large plastic lever to Verriegellung the Panhead is somewhat awkwardly shaped and scars therefore on the housing of the flash along if you're not careful. Is a bit cumbersome to use and leaves unsightly marks. The cap is long enough to accommodate even the modeling light (is not at all flash so because then the modeling has to be removed before the flash is transported). Thus, the pack size increases slightly, but I find it more practical.
The remote control is simply pushed to the hot shoe and has no lock, so they felt quite loose. In my tests, but there was no connection problems.
The softboxes are building something stubborn and in construction by manual they were always a little "wrong", but otherwise functioned exactly as they should. Next time I'm going to be slightly different from the plan, and try if I get them so evenly mounted.
The stands seem robust, but one you notes to the budget-conscious construction. When pushed together you can feel that there "simply placed a spiral spring into the pipe" was. Works, does what it should, you can tell simply. Unfold the legs of the tripod is connected at least in my specimens with a little effort and some fumbling. Perhaps gives to some use, as a permanent condition with regular use but it would be annoying. Since I anyway rarely need the flashes, but I can live well with it. The included carrying cases presuppose that the tripods and hence the springs are completely pushed together. This makes them suitable only conditionally for the storage, at least if you put increased value on the suspension performance.
The included case for the set could be in my opinion a bit bigger (especially longer). The stands do not fit in the pocket and in a little more length would not be sorted quite as elaborately the flash heads. Schön would be a way been the Speedrings (the connector softbox flash) better accommodate or settle for this a small cloth bag, so that these metal parts not just lying around on the flashes. But maybe I'll find there's a different packing possibility.
Conclusion: For flash-and-promotional price of 339 a successful entry-level package that offers more flash power and hence more resources compared to other sets in this price range. Without offer (and with my experiences described above) I would look also slightly more expensive sets and then weigh in peace.
