Query: What you really need to keep the notebook cool is ventilation

I bought this because I believed all the crap about the gel dissipating the heat better. However, the bottom of the pad cannot dissipate any heat because of its thickness. The top of the pad is where the laptop is so there is nowhere for the heat to escape. It will only prevent your lap/thighs from getting hot.In my experience using it with my macbook pro 15 inch, the laptop temperatures were not affected at all!Also, the white surface where the laptop is supposed to go, is extremely slippery. So the laptop will slide off the mat, which is a huge downside.So believe me, and do not buy this 'notebook cooler'
