Leupold's warranty and customer service would be difficult to fault for anything but the reason I've stayed with Leupold scopes is they just don't fail unless abused and it has to be severe to take Leupold out of service - I wouldn't use anyone's low end scopes but the VX2 line isn't low end - Nikon makes really good scopes to though - A couple of times lately I've walked past the scope counter in SW and actually listened to the guy behind the counter running down Leupold products while talking up Vortex as the "new and BETTER" stuff .... it just ain't so - not saying Vortex is crap by any means but there's good reason why Leupold is in the group at the top of the list, actually several reasons ... quality, innovation, engineering, customer service, solid warranty - If one were to be able to drift around the Leupold factory and corporate offices (in Beaverton Oregon, always has been at the same address) one would hear quite a few German/European accents which I've always found interesting ..... I've been treated like a rock star every time I've ever taken or sent a scope in for a checking out but I've never had one fail me while in the field, never - you can buy a used one on ebay and send it to Leupold simply to "look it over" and they'll take it completely apart and check every last detail for $0.00 except nominal shipping and not always that - THAT'S a good warranty
