Review on Stay Cool and Efficient with Lamicall Laptop Cooling Pad - Five Fan Portable Stand for MacBook Air Pro, Dell XPS, HP and Alienware Laptops up to 15.6 Inches by Randy Jagers

This cooler does a good job in this price range. It's easy to use and produces enough air for my 15 inch laptop. At this price I should have known there might be little things about this cooler that I wouldn't like. For example, it's height adjustable, but the retractable tabs don't have rubber on the bottom of the legs. So if you have a wooden table like mine, it's no good. A USB hub has two ports, but the device is powered by USB, so you forego a port on your laptop to power the device and use one of the two ports on the device. Basically it only compensates the port you need to use for power (2 ports on device - 1 port on device for power - 1 port on laptop for power = 0 extra ports). In general, the device does what it is supposed to - it cools the laptop well. But the little touches that would have made this a great device (a USB 3.0 hub with additional ports and rubber feet on the height adjustment tabs) are simply missing.
