Bought it for work and got it through the Corporate Express / Staples catalog...unfortunately this is one and only laptop cooler they carry. Technically cooler does work as it brings down my MacBook Pro 15.4" by a good 10C. The fan blows air direct at the bottom of my MBP and vents out to the sides. On average I'm running below 50C while working on non-graphic stuff which is not bad at all. But here are the cons: 1) it's noisy as hell; the noise level is almost equivalent to running my internal fans up to 6000 rpm, 2) the ergonomic is horrible and there is no way to adjust the tilt angle, 3) it's made with cheap plastic; the back legs could collapse if you accidentally bump into your laptop. Overall, Belkin continues to disappoint me so only 2 stars...
