The fit is optmal, the notebook sits on it very well. The three built-in fan to sit just above the "central axis" of the pad, should therefore not be appropriate for computers that have their vents far ahead or far behind the housing. The pad should have been used rather stationary is designed less for mobile operation, it shows what appear based but a pair of corners and edges slightly sharp if misused.
The fan unit has on the bottom NOT guard or the like, therefore, is not recommended as a knee pad or on soft ground by use. Here reference should be made to a specially designed pad. Who uses his notebook stationary as a substitute for a large desktop computer, has the pad, however, a stable, visually appealing surface.
The volume of the fan I would not indicative as disturbing. After a half year term, although they have risen slightly in volume, but are not louder than my notebook integrated fan when operating under full load.
I can not say much because my laptop apart from the Inter fans Gierten only a "vent" has, to the processor via the cooling capacity. But he loses in operating good 4 ° C by the pad, the bottom of the device is not warm. Therefore, I think that the pad already done good service.
However, only negative is: Adjustable fan would have been more advantageous. Now you have but one "on / off" installed, which would have otherwise Revoltec solve.
A gimmick has the I particularly liked is the supplied USB connection cable. This is wound on a tiny cable drum and is pulled out to the required length. After using the cable rolls then selbsständig again. One could compare the principle with a ski pass holders. No excess cord longer hanging around somewhere or lying around, special only as much is really needed also.
Due to the positioning of the USB connector (right) and the cable length, the connection of the pad could cause problems if the laptop has USB be left or left behind. In this case, might be to get a longer cable.
CONCLUSION: Actually, a stable, well-functioning cooling pad in chic look. Ideally suited to use as a fixed base for the people the laptop as a desktop replacement. Slightly larger ventilation area would be desirable, however, ranges from. In my view, absolutely not suitable for operation in the bed, on her knees, etc.. Since there is a risk accidentally the fan to block or put into it.
I am happy.
