I bought one of these Lapinators because of the claims that it keeps your laptop cooler and better ventilated. I had had occasional problems with my laptop overheating in the past (I have a Toshiba Satellite) and thought this would solve the problem. Well, instead it had the opposite effect, in that every time I placed my laptop on the Lapinator, within minutes my laptop would overheat and crash. So I sent the thing back, even though it took over an hour of my time plus the expense of additional postage (and no refund on the original shipping fees), mainly so I could be free of a guilty conscience by not adding more non-biodegradable plastic to the landfills. Save your money, your time and the landfills by buying something else.
