Summary: This product does exactly what it says. It is fairly quiet and keeps my system running cool. It has 2 positions for height, but I've found that the default, lower position works fine for my purposes. The pad itself stays cool to the touch all the time and keeps your computer extremely cool most of the time too. I bought this device because my computer kept overheating while trying to game. I haven't had a problem with my computer since.
Summary: The fan keeps my computer very cool. I am pleased with that aspect. The adjustable legs are annoying. I have had a leg collapse while I am typing. This has happened frequently. Apart from the legs, I am pleased with my purchase.
Summary: I bought this for our laptop (an old HP) because its fan went out. Before using the fan the laptop overheated minutes after turning it on. Got the fan and it works once again. Bittersweet. Guess I won't be getting a new laptop now. Very pleased with how well it works. Plugs in via USB. Mesh top and large fan in the center. Better than any of the fans that I saw in the 3 stores I shopped at before purchasing here.
