Does precisely what it says it does. Works like a charm. Speeds are as advertised. Nothing much other than this can be said about the product. If you wanna use it with a DSLR with an adapter and you are shooting video, you might wanna consider a faster option, or just buy a full sized SD card. Other than that, I can't see how you can go wrong with this.
