Open an electric toothbrush?

    Have an older Broxodent electric toothbrush. The connection where the
    cord enters the brush is loose. Work-around is to hold cord to case
    with a rubber band.
    But I would like to do a real repair. First step is to get inside that
    end of the brush. So... Has anyone opened one of these puppies?

    The one I opened was rechargable. I did it carefully so as to not destroy
    the lower buisness end where it sat on the charging stub. It was water
    damaged, but I found out that it uses 20 KHZ to couple into the battery
    charging circuit.
