A few years ago, I purchased what I thought were genuine Nikon batteries for use in my cameras.
Once they arrived, I took a very good look at them and determined they were, in fact, counterfeit.
( They had official looking hologram stickers and whatnot, but were not the real thing )
I returned them and ended up purchasing the batteries through a local dealer instead.
Now, while some will say " What's the big deal ? ", if a problem develops within those batteries and
it ends up destroying your $$$$ camera, you can bet Nikon would tell me " Too Bad for you ". Otoh,
if a genuine Nikon battery does the same thing, Nikon would probably be a bit more sympathetic since
it is their official product that I'm buying.
Bottom line: If I cannot trust Amazon and / or the sellers who operate through Amazon to deliver genuine
products, I will simply cease using Amazon to purchase any of it.
It's that simple.
