ALL joysticks will eventually wear out and need replacement parts, more so if you use your stick as often most AH flyers do.
If you're that disgusted, you can guy the switches, pots and such for next to nothing and just replace them yourself.
Even if its not under warranty, they do the repairs for next to nothing anyway, and return the unit to you tech checked, cleaned and polished.
Try using a Wingman Extreme, I guarantee you'll be alot less happy than you could ever be with CH.
