Save your money for something better - LaserLyte Universal Laser Bore Sight

Purchased a new unit to replace my "old" unit which worked perfectly.....until the switch wore out or a solder joint went bad after 4 years. Didn't know it had a 3 year warranty or I could have sent it back after the first sign of the switch going bad. I had to adjust the old one once to recenter the beam and it was pretty easy to do, had instructions for it as well. New unit did not have instructions on centering the beam and the company epoxied the adjustment screws in place. I checked new unit for center. It was an inch off at 8 feet - that's a 2" circle at 8 ft. Do the math and you wouldn't even be on the paper at 50 YARDS. I wouldn't give a plugged nickle for the new units. I narrowed down my switch issue with my old unit to the spring that rides against the batteries. I'm a design engineer and expert shooter so I know what I'm talking about. If you have a fix, please advise. I contacted the company and got that I did everything they would do to get it to fire up correctly then told to just purchase a new one. Of course, I waited like 7 or 8 years which I can't gripe much about, but a switch like this to go bad? I've also done endurance testing on components and assemblies and never had a switch wear out like this. Would not recommend getting this unit no matter how many say it's one of the best. Well, it isn't good enough for the money.
