My former career afforded me the opportunity to have as many as 200+ Leupold optics under my control at one time. I do not say this to brag, but the only guys who have seen more failures of their products is their own customer service.
Their customer service and representatives have been really easy to deal with, was actually on a first name basis with a few. Normally I would have a scope (rifle or spotter) back within a few weeks. In the past 15 years I've had two of my personal rifle scopes crap the bed within a week of leaving for out of state elk hunts. Both times they overnighted me scopes, one a loaner. The other half dozen times I sent in personal scopes the turn around was pretty fast, 2-3 weeks.
My last dealings was earlier this year:
I sent back an upper end scope that wouldn't hold zero when I returned from an elk hunt. Took over a month (probably closer to two) once they received it, and that was with one of their tactical reps pushing it through.
Same thing with my buddy's new VX5 he got for Christmas. When in the process of checking function/mounting/zeroing, one of the turrets literally fell off guts and all. He received a new one.
