Title: Isn't worth the money
Review: I'm on my 2nd one. It's fairly quiet and seems to cool the laptop but, after about a month of use the fan started making noise like it was off balance. The only way to stop it was tap it several times. As long as it was running it was fine. Turn off the power and then add power it would make noise again. Tap it again and it would be quiet. One tap too many and the cage broke, so I bought another. After a month or so it does the same thing, fan gets noisy and I have to tap it again and again to shut it up. Going to buy a different type later. Will not be getting another one of these.
