Apparently they solved the QC control problems of lenses coming loose, and as long as you purchase a newer one they dont seem to have these problems anymore. However if you are purchasing from someone who doesnt move scopes very quickly you could still get one of the old batch. (Personally if I was buying one I would get it from Plainsight Solutions here on CGN because he moves a lot of volume so I could be certain they are not old stock) I was in Sudbury and stopped in at a sporting store and had a chance to spend about 2 hours viewing them one afternoon. I was quite skeptical but once I compared them to Bushnell 4200 & 6500, Burris tactical and Leupold I was very impressed - They have amazing eye relief , clarity and brightness especially when I compared them on the higher magnifications - I was looking at the ZA 5 3-15x50 and I believe it had 1/8 MOA adjustments which can be quite nice for longer range target shooting ( I looked at a few so I may have gotten the 1/8 MOA mixed with one of the other Minox). The only scope that I liked more out of their selection was the Zeiss Conquest which had a crisper feel to the turrets. AS a mid level scope they give you a lot of quality for your $$. As always it depends upon your eyes, budget and purpose.
