one thing i'm glad for is this product works rite out of the box, not only it works but it also do a great job: HC? yes, fast? yes, but not that fast cuz it's only class 4, but hey, beware of your own electronic that can handle up to a certain of classes.  Kingston brand is alrite, i have couple products of it and they last for a quite a while, well it lasted longer than PNY and Sandisk.  bottom line: good product to own.
