    After wafting and wavering in the world of owning 20+ usb drives at 1 or 2 GBs a piece, I finally decided to make a change and get the 128. Storage simplified. Life simplified. Great price too!

    Incredible to be able to carry around this much storage in a little thumb drive. I also highly prefer this form factor that lets you retract and protect the USB connector. Highly recommended.

    Works as advertised. Tons of storage for a great price. The only thing I don't like about it is the casing is pretty thick and it makes it tough to insert into PC's that have multiple USB slots.
