Summary: This cooler is meant to be used on desks or tables not on soft surfaces, like your lap. I hope it will last longer than the last one I bought from Walmart, which was designed for lap use, but had a very weak fan. So far this laptop cooler worked fine and that is why I gave it the maximum rating.
Summary: My 17" laptop previously grew hot to the touch after extended use -- especially during demanding applications such as an hour-long Skype session. The Coolermaster X-Slim NotePal Cooler solved the problem IMMEDIATELY. My laptop hasn't run hot since I got the cooler.
Summary: So far, this is working great. It's not silent but it's quiet; I don't even notice it when I'm not thinking about it. I'm also a fan of the USB plug, as it has an input on the other side, so it doesn't take up a USB port.
Summary: I purchased this cooler some 2 years ago and it has yet to fail me or my laptop. One time the inner usb wire came loose and jammed up the fan...I had it on for several hours after this (as it runs quiet enough you don't notice it) and when I did notice I was afraid I would have to replace it.
Excerpt: Light, simple, and efective. I can use my old overheating labtop indefinately now, and the base never gets more than slightly warm. Not quite "silent" like the box claims, but no worse than a medium-large desktop PC's internal fans.
