In the first few weeks since I have the flash in use, it has proven to be versatile and reliable. A studio flash to take away all possible Location is a blessing! It has the high flash output available everywhere without having to worry about the power supply on site. The battery charge is with me so far always served (greatest use were about 400-500 shots in a circus tent at about a quarter of the flash output.) In particular, the large control range about 7 (or is it 8) stops in third stage is useful. So you can still work with the very strong lightning in the macro range. The remote control with the power control and switching on the modeling light from the camera's comfort factor that can not be overestimated. In particular, it is thus possible to mount the flash in difficult to access locations and then fully to regulate from the camera. The service I find sometimes a bit difficult due to the multi function keys - I can not remember that good keyboard shortcuts, if I do not need every day. The manual is probably translated from excellent Chinese food in poor English and therefore useful only in very carefully, nachdenkendem reading. For that I have deducted a star. Could I deduct half a star, that would have been enough, but the manual is part of the product and this is not much good ... Conclusion: I had bought this as a flash First, I would not have as many studio flashes, because this is sufficient for many purposes.
