The flash is very well made (although he comes from China and is relatively cheap). Nothing creaks, nothing is wrong turn and everything works as it should. Only the test button with which one approaches the flash is very hard to press. This just sits too deep in the body. I could just press the button with your fingernail. All other buttons are built differently and have a very pleasant pressure point.
The Bitz is very strong with its guide number. Without the integrated diffuser which Lcihtintensität's almost too much (even with short focal length). I recommend additionally to buy a wind-up diffuser. For portraits this is necessary.
The supplied foot is very stable and helpful. A protective bag which unfortunately is not of such high quality is, after all, also included.
The flash does not support TTL camera. So he's fully manual! So you need to know on which levers to pull needs to adjust the exposure of the photo correctly. For beginners this is a tremendous challenge.
I recommend this camera flash only experienced users and possibly only as a slave flash for indirect lighting (as a slave).
