      Comments about Solidtek Mini USB Keyboard with Optical Trackball:

      The keyboards were used in a kiosk application, and the size and price were perfect, but the track balls, as they so often do, wore out quickly.

      Admittedly we provide very heavy usage, but I would have preferred them to last a little longer.
