Over the years I have sent several Leupold scope back and ALWAYS got great service. Many years ago my Dad fell and broke a lens in his older 6x Leupold scope (a pre gold ring model bought in the 60's). They called me and said it couldn't be fixed and what would my Dad like in place of it. Sent a new VXlll 3 1/2 x 10 at no charge, which was a brand new model at the time (which was not what I asked for). When I called customer service, they said a good customer like my Dad deserved an upgrade.
I also broke a pair of Nikon binos in half. Sent them back and expected nothing in return. Got a new set of 8 x35's back, no cost. I had heard that Nikon was pretty bad about warranties, but sent them anyway. Was I surprised.
