I liked the advertised features: blinking mode, ambidextrous switch, compact size, doubling as a mount, but it doesn’t work. The sight seems to have a good amount of horizontal adjustment, far more than a telescopic sight, but (top mounted) the laser dot is way far to the right of the point of impact and can not be adjusted to that point. I’ve placed the unit on to the Weaver mounts of 2 different rifles both of which work fine with scopes (one of them with two different scopes); in each case the LaserMax is way too far right to be adjusted on target. Useless. Because this defect is so large it’s likely a manufacturing defect. I’ve tried to contact LaserMax without success. My unit came with a warranty registration card; on the bottom of the card it said, “For your privacy, LaserMax encourages you to complete this warranty card online at www.lasermaxusa.com.” That site does open, but when I click on product warranty something starts to load, but never completes loading. I’ve tried several times. I don’t usually write reviews, but this is so bad, I hope I can save someone else your time & money.
