Bought two at a very good price from Great Offer Stock..com. I had never owned a gun laser before but was very pleasantly surprised to find how great working they are, both during the day and at night. I put one on an AR. Found that the adjustments were easy to use to 'O' the laser. During target practice the aim was dead on the target. I'll be putting it to good use in the future. I did give the other one away as a Christmas present, and it was very well received.
