I bought a Nissin Di700A flash light with Air Commander just less than two weeks before writing this review. Product was competitively priced and arrived in the time-scale promised with due notification by Fotosense of its impending arrival. I have had only one opportunity to test/try out the Nissin. It is neatly built with clean smooth finish on the surface. The battery capsule/cassette took a little time for me to grasp how to load and install but I guess that's my failing. Anyhow, it worked perfectly with approx 12 exposures that I captured - more to follow before I know if it is perfect in every way but looking good. Happy to recommend both Fotosense and the Di700A in the light of this limited experience. Incidentally, the Di700A on registration of the product qualifies for a 2 year warranty - with Minox.
