I've been burned by most of the non-Leupold brands and if there is one I missed I know someone that has been burned. Leupold service is incredible. Also, bought 3 clearance Simmons 6.5 x 20 a year ago, currently two work. I understand it's warranted for life to the original purchaser; but, just gonna use it for spotting and stick with Leupold. Nikon would be my second choice, got one that hasn't been a problem and don't believe it's quite as good as Leupold.
