Support Lavolta Cooler PowerBook Apple Macbook 13 "/ 15" / 17 "(Air, Pro, Unibody, Retina) - 2x USB 2.0 Hub ports - 1x Fan - Black (Electronics)
It serves its purpose: support a laptop computer, and cool (mine has no fan, broke down and very expensive to repair). I just regret that there are no multi-speed fan. It can also turn off if you simply passive cooling. Look a little cheap, but once
