My pins got bent because of a faulty SanDisk (Nikon recommend).:thumbsdown:
SanDisk lifetime guarantee didn't want to know because I can still use it in a card slot on my PC. :thumbsdown:
I now only use Lexar pro cards, good tip I picked up on here from Woodsy

(photographer of the year) leave your card in the camera and use Nikon transfer. Not much help if you are on a shoot and have to use more than one card but for the odd few shots it's ace.
