    The 128 GB SanDisk-Ultra is a great value for the price I actually paid, with the built in security features to help keep your files private. I have not only recommended this to others, I have actually given them as gifts to my friends with computers.

    I bought this for a very 'mature' friend who was bemoaning the fact that his new car no longer has a CD player and hates the radio...so I loaded this stick with his favorite tunes and he's over the moon delighted. The interface in his car makes it so simple to operate, and he's got all his favs in the car with him. Perfect gift!!
