Just a little fun fact...
Back in 96 when I got my 64, I looked at the analog stick and how it was designed and immediately found a flaw. Maybe it was intentional since Nintendo sold replacement controllers, but I knew that the thing would wear out faster than I'd want it to.
So I opened the casing for the analog assembly and coated all the parts, especially the bottom "dome" which the stick glides against, with lithium grease and popped everything back together.
My controllers are over 14 years old and have zero wear to the analog stick. They still feel like they did when I first got them.
