Query: Piece of junk!

This thing is an absolute piece of junk. It lasted only 2 months and starting having problems with the fan in the first month. Some of the flimsy plastic fan blades got stuck and I had to open the cooling pad to remove the blades or to trim them back. Then the wire that goes from the usb port to the pad began to quit on me. I had to move it a certain direction just to get the fan turning again. I wasted $25 on this thing. Don't buy it!
