It's just what I hoped it would be! I bought two of these because of the great prices, kept one and gave the other as a holiday gift.
The device is recognised without issue on the Mac and PC's, the data transfer is very fast, the retractable mechanism is great (so far so good).
I've got zero complaints so far, and recommend this above the SanDisk Contour. The Contour was extremely fast, but the retract mechanism failed within 2 months, despite limited use. The drive picture here uses a different mechanism and should avoid those problems.
