Delivery etc. all worked great as always, thx to Amazon!
Now for the device:
+ The USB connection cable is both right and left can be laid and has a good length
+ The unit runs very quietly
+ Nice design, even the great laptop is safe
- The fan power is ... well rather poor
- The ventilated area is approximately 10 * 10cm and which are centered at the top edge of the laptop display
(So pretty far away from the typical notebook ventilation slots)
Unfortunately, the cooling does not matter where it is needed.
Even when I had removed the cover of the notebook and placed over it so that the fan was directly under the GraKa,
has just reduced by the poor performance of the temperature times around 6 ° C. This is for the same performance
the integrated Notebook fan simply too little.
Conclusion:
Lets use itself, so it is not too hot on warm days on the lap.
For gaming Laps absolute bad buy because of poor performance!
As the with the vents is everyone must look for yourself, for me it was extremely unfavorable.
