I really like the aimpoint. You can leave the dot on for a year and it's bright. Try leaving any other brand dot on for a couple of months. It will be dead. Try throwing another brand dot sight across a room. Most will be broken. The aimpoint will be working.
I just stocked up on beer, dry ice to stock the fridge, food,propane, and flash lights. I have a pretty good home gym so I don't have to be concerned with gym closings. I'll train by candle light.
