As with many things Targus, this is overpriced cheap plastic and it may keep your lap cooler, but doesn't do a thing for cooling your notebook in any possible way. It also in the Unfolded position, 1. doesn't fit widescreen laptops well as there is no room for a mouse and 2. probably will break if I lifted it onto my lap. I use the folded position to use the tilt function. It's still overpriced for what you get. I'd say it's worth $10 but probably made for about $2. I've owned this for 2 months now and the rubber standoffs don't work very well anymore and the notebook doesn't stay put in tilt anymore. (that and it will eventually rip my COA's off the bottom of the Notebook.)
