good reviews. Aluminum.
sucks not blows though , still works

$-1 after GCO lolz

Have one - well built, but I wish these were thinner...

It works great, however it's not very comfortable to actually put on your lap.

It works great but be aware of Antec rebate. They don't pay their rebate lately, especially from buy.com google check out.

yeah these do work very well!

Do they have a size for 17" laptops?

"It works great, however it's not very comfortable to actually put on your lap."

Agreed. It's like putting a metal slab with all sorts of abrasive edges on your lap. It works, but I'm sure there's better options if you're willing to pay more.

does it blow air upwards or away from notebook?
