I've had a pair of Leica 8x42's for 20 yrs.Despite being old and the lenses needing re-polished,they perform just like they did 20 yrs ago.I also own Swaro 15x56 and a Swaro spotter.You can't go wrong with either.I have not dealt with Leica customer service,but my hunting buddy had an issue with his rangefinder once.He sent it in and they sent him a new one post-haste.
