Think these batteries are real?

I've never seen a bad SD card. To me, they seem like a dime a dozen. For the Sony A57 at least, there is also no point in getting anything faster than class 6, because the camera won't write faster than 45mb/s anyway.

So, whatever I deal I see at some trashy thrift place I walk in to form time to time. Price, class 6 or better, size, all good, buy. Not saying that there aren't any problems with arbitrary cheapo cards, but I just have never encountered any problems. All my cards except one, is some weirdo brand.
