I have had this product for almost 2 months now. I have a 17 inch as well as a 14 inch that i use on this, and while it does provide ventilation, it doesn't do enough to cool down the temperature when it gets high. For the price i paid for it, i expected it to be much more efficient at cooling. I've had to lift my laptop off of the pad on occasion, and literally use a magazine as a fan to cool down the temperature. This product definitely needs a fan built in. Furthermore, the rubber covering the vents has peeled off in various spots from the weight of my 17 inch laptop, while holding it at an angle. I would have expected the rubber to hold up much longer and withstand the friction of heavier laptops. I wouldn't buy this product again. I felt ripped after being able to use it this long.
