Locate the flash just great. The functions are practical and the photos are optimally illuminated. The discussion on the overheating I do not understand, who flashes for several minutes in front of him? For such Blitzer there mEStudiogeräte. Had incidentally also issues a German manual to get the delivery of the product by Amazon. Even with the replacement only an English manual was there. So just down load from Nikon is not, because the pressure is locked. Why, I do not understand, that's no business practices! But I have done it and now have a German manual even printed in A4 size.
