Does the card look like this:
SanDisk® Extreme® HD Video SDHC? Cards | Camcorder Memory Cards
Sandisk does make a "HD Video" card that is a slower class 6 card. I would check to make sure there is not a mixup (of course labeling does change, but none of the class 10 Extreme cards pictured on the internet have that labeling). Funnily enough, Sandisk does not list a 32GB capacity of that version. I'd be careful here, it is possible that things got mixed up (or worse that a return where someone had swapped the real thing for this fake got mixed into their stock). Do check it's performance speed wise, and if you have any other worries, just call Adorama.
