Buy a roll of duct tape if you get this.

I bought this about a year ago now and it's still working so that's a plus. It gets louder and louder with time but it has kept my computer going for the past year without overheating so it does its job. Down side i have to duct tape it to my computer because the round pieces that hold the platform that slides under the computer broke shortly after I bought it. The rubber over the wires on the usb cord separated from the USB plug so I had to use electrical tape to keep it from falling apart and The noise is pretty loud so if you work in an office setting or spend a lot of time on the phones I would suggest looking into something else. Overall I wouldn't purchase again and it's about time to upgrade and drop all the duct tape.
