If this is the model with the fast focus eyepiece, it was a PITA to keep it where I set it.
The AO was easy to adjust, but the eyepiece lacks the typical lock-ring of the Leupolds. I seemed to be moving it every day at some point, and chasing whether the AO was out of adjustment - or the eyepiece focus.
I though the eyebox was out of wack as well, but it was a minor one of several things I didn't like about mine.
