Save your money! - Sightmark Triple Duty Compact Green Laser Sight

I ordered the unit direct from Sightmark. The first unit received wouldn't turn on. Returned it and it took a week after they received the first one to send a replacement which supposedly went through QC. I got the second unit and installed it on my pistol. The laser turned on and was visible with indoor lighting. Went to the range and tried to align the laser at 15 yards on a covered range in daylight. I couldn't find the green dot anywhere down range. I started aiming the laser at the ground in front of me slowly raising the sight to see where the dot disappeared. The dot vanished 10 feet in front of me. The write up on the Sightmark website clearly states "Visibility extends to 50 yards during the day and 600 yards at night." I called Tech Support and was left with the impression that I didn't have a warranty issue because of the poor performance of the laser.
