perfect for your daily transfer. As a student i used everyday to save my work and transfer file from home to school. I even, occasionally, use it as a media tool ( to watch movie on tv).
I would not recommend to let it plugged for long period ( more than 2 or 3 hours) as it tend to get really hot. It doesn't feel secure on any usb port that are horizontal, enough to transfer what you have, but it is better on vertical usb port.
Even after 6 month of daily use, carried in my jeans pocket with other keys and a couple of drops on concrete there is only a few scratches.
