As previous customers running genuine Canon flashguns I let myself be fooled by the great recession. The flash should be a kind of last resort (ie, it should always be in the car). Have at the price no miracle of technology expected, but as a plastic stuff I did not expect. Even when compressed with 2 fingers crunches and cracks it frightening. The hot shoe is screwed, without fixable quick coupling keys that react times, sometimes not, a housing, so thin that accidentally dropping it would lead to a total loss, and a non-fixed lockable flash head. Top. For inner life: the battery compartment a note: not suitable for Li-Ion batteries. Have tried it but gave wrong Flash services. On the EOS 1D X and EOS at the 1M Mark IV, there were also with NIMH batteries very often wrong flash performance, the EOS 70D everything fit perfectly. So a flash of pure amateur cameras. The charging times with fully charged batteries are quite long. The flash tube is the flash of a loud popping up, somehow does not sound healthy. OK, I'm used to the Canon flash, nevertheless a clear NO THANKS for this part.
