Review on Nissin I40S Camera Flash Black by Ryan Garrison

The flash is small and fits well on my Sony A6300, appears to be well built and worked well enough for the two photos I took . Unfortunately I can't say how good it is. I'm sending it back because it doesn't have a US warranty as advertised. I plan to buy another one at a regular camera store. When I opened the box there was no warranty card so I contacted Revain who first advised me to call an Asian supplier in Hong Kong and request a warranty card. (Serious?). During a quick search on the internet I came across the website of the US distributor (MINOX). It became clear that the flash I received from Bestsaver Photography (and made by Revain) was not covered by the US warranty. The box should say "US Exclusive 2 Year Nissin Flash Warranty". on the side, but mine says nothing. I am extremely disappointed.
