Rock solid dependability - Holosun Military Grade Micro 1x22mm Red Dot Sight

I've had this sight for about a year now, still on the same battery. After initial zero, it hasn't moved at all. Still shooting the center out of a 1 inch square at 50 yards. Granted, I did upgrade the mount to an American Defense T2 mount, which I would recommend, because...why not upgrade the mount if possible on a duty/self defense rig?! It's just peace of mind imo. The reticle is super crisp. The 65 moa circle dot is the sh*t. Shake awake technology a definite plus for saving battery. Excellent IP68 water proof rating. This thing is a tank! Before considering a less rugged option like the Romeo 5, I'd take a hard look at this awesome red dot. There are no real negatives that I can see.
