Just got one. I'm wondering what you think of yours and how its held up. Seems to be a pretty impressive redot for a 180 bucks. Once you turn it on it will go to sleep 2 minutes laying motionless and turn back on with even the lightest touch or movement. It would be great for a self defense home gun. You can leave it on indefinitely and it will sit there sleeping until you grab the gun in the middle of the night. Anohter cool thing is this model uses aaa batterys which a guy can find about anywhere. Dot nice and clear too. Not all fuzzy like my vortex red dots. Saw some on line testing of torturing them and they seem to be a pretty rugged unit. No there not a American made aimpoint but then there not 600 bucks either. Ive got a couple aimpoints from back when I was working and price didn't matter so much.
