I purchased a flash drive online from WalMart about 2 years ago. I didn't have any problems with it. I just used it for storing college papers and assignments. I didn't have any problem with it. In fact, I still have it. I just ordered this one because I need more space. What I like about this new flash drive is that it's sleeker and it's cuter than my old one. I would highly recommend this product to anyone especially if you are someone who needs to store huge amounts of data.
