Looking for a laptop stand where I can change the angle, I was able to find at BESTEK. The then another ventilation is available makes it overall a super package. The fan can be connected via USB to the computer and turned on with a continuously variable wheel and regulated. The ventilation of the volume pretty quiet even at the highest level, ranging from the MacBook to cool well. The build quality is fine and the price confirmed all. Benefits I am doing all of my 13 "MacBookPro. And it is left and right from the MacBook just under 1.5cm square.
