By my Ph.D degree, I have to travel a lot. I also have to work a lot on my laptop. But, my laptop, like for others, is always lagging due to overheat. To protect itself, laptop processes slow down and wait for cool down. I search for a solution. Fans ? It uses my battery too quickly. I was looking for something easy to use, which doesn't require energy and cheap. I get the idea while working in USA. Now, I am living in Asia. Tropical temperature should drive my laptop crazy if it wasn't protected by CheapCool. I studied specific materials, foam, glue, design to avoid troubles with plastics, brands... With this commercial version of CheapCool, I am perfectly satisfied. Why not you enjoy it too ?
