Query: Works but. . .

I bought this to cool my 12" PowerBook. The pad itself works well -- the weak link is the power cord. The first one had a bad connection in the plug end. After repairing it with some home soldering and electrical tape to cover the wires, it worked well enough to wait for the replacement cord from Targus. (yes, I had to scrape away the housing to find the wires). Within two weeks, the wires into the on/off switch were falling out of the switch.
