I received this flash with 2 days ahead !! great, very well packaged, and with a diffuser that will be useful. I am trying to find its functioning, I have understood certain things, but obviously a pity he did not notice in French, for me big downside because I've never done English and even fewer Chinese !! but I found! if money is a good product, I had to rely more than double for a flash nikon. my choice was quickly made.
