The cooler is extremely lightweight and is very stable on four rubber feet. Class that you back still show two also rubberized feet and can make the computer so inclined. The condenser is connected via a standard USB connection to the computer, and thus does not require its own power supply. In order not to lose USB port, the connector is as it were a double connector to a USB port on the top.
The whole fan is like saying extremely light, yet stable. Of course, you can hear the two fans even when they are running. To my mind they are but fairly quiet and after a certain time it takes no longer notice the noise. But even if I set the computer only on the cooler to operate without the fans, the grid surface already provides a reduced temperature of the computer. Why now blue lights were installed in the cooler, I can not say. Although is chic, but when the computer is on it, you can not see the yes.
Overall this laptop cooler is in my view a good thing. It ensures that the computer does not overheat and you can still use it in addition to make the computer run diagonally. But then there's also 5 stars from me.
