I hav had Leupold and Vortex fail but both companies did right so no worries. They fail far less than cheap scopes had cheap one fail during hunt but reall it was just old lost gas fogged. Leupold failed was bought used so who knows what original owner did only have Leupold and Vortex now. Do have great Weaver target scope. All brands can and will fail better ones hold up and warranty takes care of you.
