Well, messed around the other night, with nite vision on. Was getting into shooting tree frogs, their eyes light up! Until scope locked up, AND POA dropped about 2" at 20 yards. Had to do the 2 minute hold to shut down. Re-started, and all was OK. So, answer is NO, still has lock-up problems. I fear this thing will aggravate me one day when I'm in a bad mood, and it will meet my BFH!
