It works
Thought I was going to have to pay over $300. for a new joystick  controller for my mother's jazzy traveller which wouldn't turn on.  Then I saw this while I was searching for the controller.  Took less than a minute to change and works like new now.  Rated only four stars because 22 bucks plus tax for a little piece of rubber and nylon is ridiculous.  Still a lot better than the alternative though.
Rating: 4 stars
