I bought the 64GB MicroSD card at Best Buy because I needed one for my Microsoft Surface Pro. It provides all the space I need and for people who need a lot of space (videos, Quick Books, picture editing, games, etc.) this card is the one for you. If you don't need that much space, consider buying one for cheaper with a little less memory.NOTE: Be aware that this is a MicroSDXC format card. While most new computers support this format, many of the older computers do not (This includes all but a few tablets and smartphones). Before buying this, MAKE SURE your computer, tablet, or smartphone is compatible. If it is not, it will not work, period. For others who claim that the card doesn't work no matter what they try, chances are their machine cannot support MicroSDXC format.
