This is a serious bargain! If you were having doubts about buying this, don't. I bought this for use with my Galaxy S, and it works flawlessly. Note that the Class 2 rating has nothing to do with read speeds, and watching HD movies and listening to music off this SD card works fine - this is the main reason I bought this. Even copying data to the SD card (I had a USB Micro SD card reader available) was pretty quick and painless, but you're obviously not guaranteed copying speeds as fast as a class 8 SD card for example. Still, I wasn't waiting around for hours waiting for my data to copy.
If you're thinking of buying this, definitely do.
