I've recently (3 weeks ago) purchased the Deepcool N17 for my 14" gaming laptop. It does it's job perfectly. The surface is made out of a metal mesh which ensures you get good airflow on every spot of your laptop. The collapsible feet have rubber pads and give you an ergonomic angle to put your mobile device on. This will also increases the air exchange by lifting up the back of the cooling pad. The USB-Connection cable is quite thin but does it's job. Haven't tried the USB-PassThrough but it's a good idea to not loose an USB-Port. The fan is quiet (personally don't have any problems but I'm also wearing headphones most of the time)....view more
