If your thumbsticks are worn out on your xbox 360 controller, your probably pretty pissed off when it makes you miss a headshot on Halo 3, or when you crash into a wall because of it on Burnout. Either way its annoying and theres a really easy way to fix it. If you have a old pair of in ear headphones with the foam covers just take em off, and stretch them over the thumbsticks. There you go, they go on tight and give you a little grip. Other very ghetto solutions are tearing up the joystick so its grippy or putting tape on them, neither of which work very well. Or you can buy grips made for the controller on ebay. But this is just a really easy solution that works semi-well. Try it out, hope i helped.
