    perfect USB stick! price and capacity are well balanced. I have around 10 of those and so far none has failed, I'm using those to move my video projects, so those will get lots of wear.

    San Disk does a quality job on their USB sticks and this one obviously checks the box as well. I bought two of these for picture back ups and they work as advertised at a good price.
