The fan is great in its design but not so great in its longevity. After only two months, the cooling pad is already starting to make death sounds. Within a week, I'm sure I'll be back on Amazon.com trying to find a replacement. Perhaps it's just this unit.If it weren't for the short life, I'd give the pad a 4 out of 5 stars. The blue light it emits while plugged in is extremely bright and annoying, and there is no "off" setting or switch - you have to unplug it when you don't want to have it on). The size and shape, though, are great. I could use either laptop - a large and small one - without worrying about whether the fan could cool it or hold it comfortably.
