My wife has this document at first used together with a 15.4 "Dell and I with a 15.4" Packard Bell. At that time I unfortunately ordered two pieces. The plastic surface is heated by the waste heat from the notebook and bulges upward so that it is no longer possible to our notebooks, reasonable to draw air from the bottom and a build up of heat. This means that the fans of our notebooks constantly running at full power, no matter how high the workload. The vault no longer forms back and can also be seen with the naked eye. The conditions are quite clear Fehlkauf absolutely unfit and for me. We are no longer using the documents, because by the heat build the hardware of the notebook is permanently damaged
If there were 0 stars I would have awarded 0 stars. Now have a Zalman cooler NC2000 bought and am very happy with it. And again proves the rule: Better to have to spend some more money on a decent product, rather than several times to buy scrap and yet have nothing to the bottom line.
