Bought two of these for storing and playing back music. 16Gb in a tiny package - pretty amazing - I wanted the small package so that it would be inconspicuous in the car (on a new USB stereo). It works exactly as you would anticipate - no issues at all. However, both units seem pretty flimsy to me. When I extract the stick from a USB slot, the black plastic casing moves relative to the metal insert. I am able to press it back into place and it has not detached completely (so far!), but I am left wondering how long it will last before it does come apart.
So far it is working fine - just a bit concerned it may not last due to poor build quality.
