Brief: Highly recommended! At first I was a bit skeptical, mainly because of the term "cooling pad". Of course, it will take place no active cooling, which indeed should also be clear. Nevertheless, the fans turn my notebook (17 "with neat power) much less often, than without backing. Presumably any smooth surface has this effect, from those who want a board already set as Notbookunterlage lap. The pad has a pleasant disposition to prevent a small bulge on the front by slipping down the notebook and is pleasant with soft underside to give (z. B. on the sofa or in bed). The 17 "notebook has comfortably on the pad space and also ruscht not back and forth, assuming, of course, the rubber pads of the device are still available. I am very happy and give her no more the part.
