Agree
My personal experience with Yongnuo (model 560), bought from Artwork - Asia xxx Festival. I found the flash's indicator LED were on, and indicating "normal" according to manual but no matter how, just won't fire when trying with my rechargeable batteries at home.
At the time I brought back the Flash to the shop, the sales girl use her batteries, and TARAAAA... all function nicely!!! What a shameful experience (and waste of timesssss) because I didn't check that two of my NiMH batteries were actually out of current........ and.... until now...
So far so good, Yong Nuo:thumbsup:
