I purchased a pair of zeiss binoculars 18 to 20 years ago 10 x 32 bt, at camp in az bull bow elk they were knocked off eating table outside of tent, went out hunting could not focus right lens, sent back to zeiss they said they were unrepairable and sent me a brand new pair, of 10 x 32 conquest hd at no cost to me except shipping, that's what i call a great warranty thank you carl zeiss
