When my old Xbox controller started clicking, I knew it was finally time to replace the analog sticks. I've never changed them, but I watched a few YouTube videos and thought it was an easy fix. After reading some reviews I decided on them. I have no experience with other aftermarket analog sticks but I suspect they are well above average. They fit exactly as they should and work perfectly. I'm sure the professional gamer has some minor flaws, but for those who only play games occasionally, they're a great substitute.
