I bought this cooler 15 months ago for my ageing 17" laptop. It works wonderfully, cooling the area around the touchpad considerably with very little noise. It also helped prevent noise from the laptop itself, as it was now cool enough that it did not need to use the laptop's very loud fans. However, recently it has shown signs of wear, despite very careful ownership. One of the pegs for adjusting the fans snapped off, making it difficult to reposition them, and the fans themselves started making a whirring sound when they started up. This would stop after a short while (usually a minute or so), but would sometimes continue for quite some time. The wire connecting the fans with the USB connector became loose and finally snapped this morning. However, I fully recommend this cooler, and will be buying it again myself as a replacement.
