I debated between 4 stars and 5. The scope itself deserves 5 stars: clear glass, positive turrets, reasonably short and lightweight, fixed parallax at 100 yards, simple reticle, great value. Everything I specced, except I might have overestimated what 9x could do in my situation. I have several 16x AOs and SFs, and I knew that they were too much. I dialed them down and waffled between 9x and 12x. The 12x equivalent ProStaff is heavier and two inches longer, so I went with this model. The jury is still out on whether I made the right choice, but you sure can't fault the scope.
