My joystick started squeaking after 14 months and the buttons started to register twice while pressed once. Steam support told me they are willing to fix it for like 200 USD, but no warranty after 1 year. It was a pleasant conversation but I hoped to get it fixed for free (I know its unreasonable after warranty) Glad to see they still making some exceptions. Good for you!
I decided to buy my own buttons and replace them for a fraction of the cost.
