Quote: My IBM ThinkPad laptop rested perfectly on the cooler, without slipp ing at all, and at just 0.6 inches thick, the cooler was found to be unob trusive. The USB cable was the perfect length, as the power plug on the c ooler was on the opposite side as my USB ports. I usually use my laptop a s I sit on the couch, sometimes for hours. Things do indeed get warm, and I am happy to report that there WAS a noticeable difference when I used the cooler….
