Decided to buy this after a lot of research into the best laptop coolers. I have a 15.6 inch laptop and this is perfect. My laptop used to get extremely hot and it started to become a big problem. This cooler does the job brilliantly and now my laptop stays nice and cool. What's more, the fans are extremely quiet and barely noticeable. You can positon them anywhere you want and they do a fantastic job. So glad I chose this product, if you're having any doubts about buying this then let me tell you, this is a brilliant cooler. One of the best buys I've made.
