Now I have to return the pad for one year in operation and had it about 3 months ago, because the fan is no longer turned. I waited mehere weeks and only got the information, it could take longer if certain parts are defective. Apart from a USB port and the fan is not active in this part hardly anything can go big break. After almost three months now I got a new pad sent. I was told no more than 6 weeks until I get it back. I am very unhappy with the long duration and understand nichtg why you need 3 months, when a new one is sent anyway. For COOLING pad: It's all right, but has now but not very big effect. The increase of the laptop is very pleasant and the laptop is not hot on your feet is also ok.
