Only works some times. - LaserLyte Score Tyme Trainer Target

after only 3 months the target stopped registering hits. Sometimes it works and sometimes it does not. I called LaserLyte and they won't help because I'm not using a LaserLyte pistol, I use a SIRT. my buddy has the same set up with no issues so I know my unit is defective but again LaserLyte won't help. Terrible customer service and they don't stand my their product. Don't buy from them is my reccomendation
