    I love having more memory on my flash drive. Computers seem to have less and less memory so it is very helpful to have 64 GB on a removable drive.

    For the price, this product is great as it can store files quickly, however, I wished it had some light indication to show if it's done downloading into the flash drive and be made out of a better material like metal instead of plastic.
