This device is a nice idea poorly executed. There are blue LED's and clear plastic, which look cool. The fans are harmless, powered by a USB plug- good idea. And it worked- for a while. WIthin a month or two this flimsy device was kaput. Its fatal flaw is the lack of a bottom plate. Result? A laptop cooler that you can't hold on your lap. A hollow core re-design, with the fans in the middle would make a longer lasting and more worthwhile device. As is, it is a flimsy toy useful only for a short while and in certain situations- ie on a flat surface.
