I had mine for quite a while and it served me very well, had an issue soon after I got it and sent it in to Vortex and they had it back to me in less than a week, never had a problem after that. I do not like Leupold's reticles but I do like the EBR-7 series, that and 30mm vs. uncommon 35mm tube tips the hat towards the AMG, but there are many happy Mark 5 owners, I do love the Mark 5 turrets.
