My Experience with Xbox Support (STORY)

I just had to replace the XB1 special forces controller I purchased when it released back in October I guess. Depends on what you play. I've played a lot of Destiny so that wears on the left stick. Oh well I'm on my 3rd controller; the Day One controller
works fine I just stopped using it.

90 day warranty is completely irrelevant seeing how they were able to send me a new Xbox 360 when it got red ring, which was out of warranty btw.

The warranty period is completely relevant. Hardly any company is going to replace something outside of it's warranty period. That's how the world works. The 360's warranty was extended (to 3 years, IIRC) for RROD issues. So no, your 360 was not out of warranty.
That's why it was replaced.

And if you want to label me as an "Xbox apologist" too then I'd seriously suggest you check my post history first.

Seriously!? SMH... it's common sense that things with moving parts wear out. Stop denying what is a known fact, wake up and smell the physics.

Do you believe there's a problem with buying new tires when the old ones wear out... just because that's investing in a product that's doomed to fail?

Controllers are not indestructible. Hence the small 90 day warranty.

Just buy a new one.

Welcome to video gaming.

^This.

The thumb sticks on a controller are mechanical devices, they're moving parts. Moving parts wear. If it has moving parts... It. Will. Wear. Out. Fact.

How fast it may wear out depends on a lot of factors and will be different for everyone.
