The USB 2.0 4-Port Round Hub not only holds your electronic devices, it rotates to accommodate your flash drive, peripherals, or other gadgets. At a size of 72 x 45 x 45mm and a weight of 65g, the hub supports Windows 2000/XP/Vista, MAC OS X, and Linux. When not in use, the hub can stack to save space. We think that the multi-colored chromatic design makes it fun to play with and we really dig the minute $12.00 price.
