A-DATA's Football Disk is available in red and black. As you can see we tested the red version. The whole stick is encased in a rubber like plastic material which is a bit soft, and seems to be able to absorb quite a bit of damage.
One of the "balls" is removable. It goes off easily, but is fixed well enough that it can't get lost accidentally.
The USB connector inside is completely standard. Given the dimensions of the stick it will even fit tighter connector spaces.
When the drive is accessed. A small green LED in one of the balls shows activity.
