content: The design for this is terrible. The end of the USB cord going to the pad sticks out at least an inch, so it's really easy to bump it if you use your laptop on your lap. A few bumps and the connection inside the pad becomes faulty. If you try to keep using the pad, you have to move the cord around to find "sweet spots" so that the pad gets its power. This is very annoying, and there doesn't seem to be any simple way to fix it.
