so:
I had always used a computer, but then have to be sold and I acquired a laptop (notebook) because I hated it ever sitting at a desk. I the laptop now on the bed / couch / easy use anywhere, I often had the problem that when I use the laptop on your lap had and the cooling grid had either obscured through my pants or duvet, or the same, the box started quickly glow, (60-80 degrees and the applications without any great power that have to operate) ... now I have the coolingpad Logitech, processed hammer and the best, it does the job !! Now the PC is in spite of full load at maximum 50 - 60 degrees, the normal I call it times DESKTOP state at about 36 degrees (ie not even fever ^^) ... The best thing about the "PAD" is it the air from behind sucks and not like the other (I call it times faulty designs) from below ...
So all in all a hammer PART! If your fun time on your laptop you want to have, I recommend to you the part really!
