I am very happy with this purchase. The module is very quiet, has 6 small fans, you can use all 6 or only 3 at the same time. The pad can be adjusted to any height that suits you. The pad works when connected to a laptop via a USB port, a USB cable is included. It has the ability to turn on the backlight change. Very well built My laptop stayed cool after a full day's work, I'm happy with my purchase. Highly recommended.
