This product will work great for a few months then break down on you. It came free with my brothers Sony Vaio computer but he didn't use it. I started using it daily while watching movies and running heavy programs because I didn't want my laptop over heating. I worked really well for up until recently now it makes this loud annoying sound and it does not cool off as well as it used. To had to that one of the fan blades fell off randomly.I usually like Belkin products but you should pass on this.I'm currently looking for a replacement with two fans.
