I have not used the warranty, but I already related my story right here in this thread of how I stupidly messed up my own scope. When I called, there was no hesitation. "Send it in." They sent it back all fixed.
This was totally my fault, not Steiner's
I don't feel quite so stupid since one other person admitted to doing the same thing after my post. They fixed his, too.
Two companies in the gun world so far have done this sort of thing for me. Steiner and Trigger Tech. The trigger was broken by one of Hornady's bad primer 6 GT rounds - I was in a school when it went down. The instructor, Robert Brantley, called Trigger Tech. We clearly explained that we thought it was the broken primers, not really Trigger Tech's fault. We were more calling to see if they had run into this before. They shipped the instructor a new trigger, and we installed one of his extras in my gun. Then he loaned me his 6 GT rifle to finish the course, along with his awesome hand loaded 110grain A-tip ammunition, which I paid for, but had a hard time getting him to accept enough to make it remotely a fair trade for him. If you ever have a chance to take a precision rifle course with Robert Brantley, do it. He is a great instructor and improved my shooting. P.S. Hornady's current crop of 6 GT primers need a firing pin smaller than .060, just FYI.
Hornady of course says that whatever cheap, paper thin primers they are using are just fine as is. If you have a larger firing pin, use 205M or CCI 450, as those are confirmed to work with a .068.
So, yeah
Steiner - thumbs up
Trigger Tech - thumbs up
Hornady - eh . . . at least they produce 6 GT, I guess. No other large manufacturer is doing it.
Robert Brantley - two thumbs up.
