Card works fine in my Olympus OM-D E-M10 Mark II.
Now I can take over 1,000 pictures on the same card. Well, not without charging a battery most likely. Don't know how many pictures one battery does, I only have two.
Bought it on Amazon. Bought it for the space, not the speed. Was a good price, and wasn't a SanDick. Should of bought a Lexar, would of been cheaper. Not sure if it's the same speed though. Transcend probably has a cheaper one, that is slower.
My preferred flash storage is Samsung. That's about the only good thing they make, unless you like paying for their name.
Also got a UV filter, for protection, don't care about the UV part. And a rear cap for my new lens. Apparently the kit they took the lens out of didn't come with a rear cap for the lens.
