I used one belonging to an elk hunting partner a few years ago. Good glass, but so hard to turn the magnification ring that I could not hold the scope on something I was looking at while dialing a closer view. That's a statistic of one.

A nephew who recently left the Navy Seals returned with one as his personal use scope. He never said where he'd been nor what he did with it and we never asked. That's probably a more significant statistic of one.
