Not too much to say really, about these things. I know people go in to transfer speeds and whatnot, but for a 4gb from the name Polaroid, I'm pretty sure people aren't betting on this "horse" to win the Triple Crown of SD cards. What i can tell you is. . . It's a real Polaroid, whatever that's worth. It came in the original packaging and it is actually 4gb. . .give or take the mathematical equation that comes out to just under 4gb. My point is, it's not 1gb or 2gb. It's NOT a scam card. It's for my 5yr old's camera and she absolutely loves to look at the pictures that she has taken all by herself. That's good enough for 5 stars from me.
