While it doesn't have the same cooling power as some of the more powerful ones, it has a lot of features that make it worth using. For instance, the USB hub turns my MacBook Pro's 2 USB ports into 4, and the ability to tilt the cooler means I can really customize how I want it to look. Also, the ability to move the fans around can allow you to get the cooler air exactly where it needs to go to help cool your specific laptop more efficiently.
