Compact, well crafted and delivered without retaining cord. While attention has to be not to put it anywhere. Beware the loss, it is really mini. Not a bad transfer rates at all: 3GB in 1 mn. And, having read some reviews, it does not heat (plug on iMac 27 "). I'll see to the USB port of my Scenic III for playing music files in prolonged use. A happy purchase.
