Review on Vivi Audio® Thumb Joystick Thumbsticks by David Caldwell

Added these to my Xbox One controller mainly to differentiate it from my husband's. They fit perfectly and actually added a bit more grip to the joysticks. They're comfortable without being too bulky and my controller looks so cute my husband won't be using it (hehe). The only issue (which is so minor that it hardly deserves a mention) is that with constant use during a long gaming session, they rotate around the top of the joystick. but they never came off, so it's easy to live with.
