Level quality flash, I think there is no problem, except that the flash Neewer turned into Triopo during travel of the article. But it works well and maybe as good as the other, it seems. But then the instructions in CHINESE or in ENGLISH is just downright insufficient to understand the operation of flash which I think is full of possibilities. We do not find instructions in French on the net. So, not being a professional, I think I'll fumble around and miss a lot of pictures before understanding its operation. Fort damage.
