I bought one last year right before a whitetail hunt in SD. It worked OK out to about 400 yds(389y actually) on deer size target but any further it had problems and only to about 700 yds on larger targets.
I thought it should work better than that and called them up and they told me to send it in. I got the new one 2 weeks later and used it this year in CO for Elk season. I was ranging deer out to about 543 yds and the furthest I got a reading was 1013 yds on a hillside if I was steady enough.
My buddy has the Leopold 1000 DNA and we thought they were both really nice and fairly equal. I will say he did have problems ranging anything past 1000 yds but we are never going to take a shot that far.
