The only scope or bino warranty I've ever had to deal with was Swarovski. The binos still worked but one of the knobs got messed up when my father-in-law borrowed it for an antelope trip. No big deal but I needed to get them repaired for an elk hunting trip. I called Swarovski and they said they could either ship me the part free or I could ship them the binos and they would make the repair for free (parts and labor)--my choice. I decided to let them fix it since they're the experts. I told them about my elk hunting deadline and they said no problem. Long story short, I got my binos back and they had upgraded about 20 or so parts on my binos and essentially made them a new pair of binos (including my knob that had been messed up). I got the binos back in time for my elk hunt and they worked flawlessly. I haven't tried any other company's warranty yet (knock on wood) but have heard extremely good things about Leopold's service also. I too am curious to hear abnout Simmons' warranty service since I own an aetec scope also (10 years now on a .338WM). Let us know the final results.
