The flash is strong and has all the items you need to put together his own strobist set. I have a total of 3 pieces with different light shapers in use and am fully satisfied. With the Olympus OM-D EM-5 and Flash Trigger Yongnuo RF-602 / N is flashed in M mode. Of course, the flash works in slave mode, ie, the flash on the camera (Master) initiates the Yongnuo (slave). The charging time is quite useful, there is nothing to complain about on the light intensity. A lightning illuminates a 109 cm Octabox out easily. A diffuser and a small Bouncer can be pushed out separately. Operation is simple and pleasant, a description in English is included. I think I read somewhere that only a description in Asian characters included, the is definitely not (longer) way. I can make this flash only each are fond of, who wants to deal with manual flashes. Who wants to have a flash for the most part "only" on the camera and wants to even do as little as possible or adjust something to your liking should be examined by a TTL system, but is usually more expensive, of course. Otherwise, you are absolutely right here at a reasonable price!
