Almost no performance

I can not explain why so many good reviews for this product have been made to me the best of intentions.
Based on these reviews I bought the laptop cooler and now have to say; I am more than disappointed.

For one, I hardly was able to determine in which direction to blow the fans, because they are just so incredibly weak.
Nevertheless, I have done with my laptop to test and have found that definitely is no difference whether the radiator is on or not. Furthermore, I find the USB cable is too short, since my laptop is a bit bigger (15.6 ") and I got the cable hardly reasonable in the socket (If you have a USB port on the back, however, this should be no problem) . Also, I have to say that the great, rugged aluminum (just as it is denounced here) could can be bent in all sorts of shapes. I do not know what to understand by "quiet", but I could set the tone of the weak fans still well above the Ventilatorenton, to my laptop to hear from there.
The only advantage I've found about this product is the pleasant, slight skew in the laptop is when he is on it, and the on / off switch.
The realization of this is that I prefer that I am looking for a tray, cover the same beneficial things and has not only 14 also costs.
It is easily done by the price, but as it turned out, as it often is with me: If you do not always buy the cheapest)
