Excellent product, I bought it by chance at Saturn, since my Macbook pretty heated when I used it on my quilt or play a little. Surprising results! The aluminum is at all boiling at a portion StarCraft 2, no overheating now.
It plugs into USB, so no need to plug it into the area, really top.
Truly indispensable if you use your laptop ds your bed or play, really pleased with my purchase :)
