Goodies: Power lightning very well adjusted iTTL, battery incorporated into the product for the same price, the number of flashes seems limitless compared to my other Flash Metz 52AF-1 and 4 NiMH batteries. Nikon CLS protocol with the pre-flashes 2 flashes respected because although they are discussed in master or slave. (Note: my Nikon D5300 housing does not have Checkout fashion on the internal flash) Fast delivery in 4 days. Cons: the displayed characters are small which makes it difficult to read in the management Master / Slave and the menu is not very intuitive in this configuration to the slave flash settings. The bag also very nice and strong does not have a flange for use attached to a belt
