Query: Not Cool

I bought the chill mat when it was on sale...and yet I still don't feel like I got a deal. The mat IS very loud, but that was of less concern to me than the fact that the USB connector is extremely un-sturdy and became damaged quickly, necessitating the connector to be held down to make the mat work. One handed computing is not my preferred method.Despite these defects, the mat gets the job done, keeping my chronically over heating laptop cool, but I came on Amazon to look for a replacement and ended up leaving this review.
