I bought two of these, one for my own laptop and one for my daughter's. She and I agree, these are just what we needed to keep our laptops cool. I was apprehensive about buying a plastic one, was afraid it wouldn't stand up to daily usage, but it seems to be quite durable and folds to a convenient size to pack into the laptop bag. It is so quiet when it's operating that I sometimes have to peek to see if the the light is lit or put my hand under it to feel the air moving. I have only seen a couple of other models in person, and they where a bit noisy. I also worried that the laptop would slip around on the plastic, but it has two little rubber feet that fold out, and they really do hold the laptop still and prevent it from slipping off the plastic top. It also has two legs on the bottom that fold out to hold the back of the unit up at a very nice angle for typing. My daughter uses her laptop several times a day for both work and pleasure and she said that it's really nice to be able to sit in a chair or on the sofa with the laptop on her lap now without getting a hot lap, especially with warmer weather coming soon.
