    It may seem a bit trite, but this flash drive was a solid purchase. It has great memory and I love that the drive retracts into its case. It is also easy to hook onto a set of keys!

    There is no such thing these day as having too many flash drives. And Scandisc has been the top for all my needs by making my 18 USB Port switching hub very useful. This one will be used to record local broadcast when I have no time to view them.
