I have one of these. Free is free, and I thank the OP for posting it .... but a word of warning.

You might not be able to tell from looking at the little picture, but it is the Stupidest. Design. Ever. The top of it is basically like a low pitch roof - it comes to a point (a very shallow point, but still a point.) The (apparent) idea is that it's supposed to lift the back of your laptop at an angle, with two little rubber feet that hold your laptop in place. The reality is that unless you balance it perfectly - and I do mean perfectly - your laptop rocks back and forth while you're trying to type. In addition, if you're not on a perfectly flat, perfectly level desktop, your laptop will slide around - because it lifts your laptop up at an angle, and the little rubber feet on the bottom of your laptop usually aren't enough to hold it in place.

I finally figured out a way to make mine moderately useful by putting a small jelly roll pan (basically, a cookie sheet with low raised sides) right side up on my lap desk, putting the Antec fan inside it and then resting the laptop on the top of the jelly roll pan. Still a bit slidey but workable if I was sitting still - really more trouble than it's worth, even for free.

(Once again, I don't want to detract from the OP by posting this, but I do have one and it is just a sublimely stupid design. It's so bad it deserves a place in the Bad Design Hall of Fame, if there is such a thing.)
