The laptop cooler of AVANTEK is a straightforward and affordable solution for a overheating laptop. I use the cooler only when playing or watching movies. He impresses with its performance. It is designed for continuous operation, however, a bit too loud, but for this it is not even necessary. A problem arose for me is, however, that not enough usable USB ports are available on my Lenovo ThinkPad, respectively, they are not usable because of the USB port of the cooler should not be connected at the same time with my HDMI cable. The supposed solution to the problem seemed to me the advertised Pass-Through Port to be, which is to allow it to continue to use the connection for another. However, this does not work on my device. The solution is for me the use of a USB port. The perceived quality is good according to the price. Rattling or vibration I do not have to report. However, you notice that the plastic used is cheap.
Logically, one can not expect miracles in the low price. All in all, however, is it is a recommendable product that I can recommend a nutzenorientiertem customers.
