Re: Laptop cooling pad
I run one all the time, because I use my notebook computer as my home computer, on for hours. I am not sure my notebook computer was intended to be kept on as often as I keep it on -- perhaps it was designed to be used for brief periods while at cafes or something. So, for $20 (on sale), why not.
They tend to wear out after awhile -- becoming noisy. I've gone through two in about a year, so I only buy them when they are on sale.
I do not bring it with me when I bring the notebook into other rooms or on the road or anything.
