Hey guys, im new here so i dont know a lot about fixing lasers, so i came to you guys. i recently got this laser to start with, 150mW 532nm High Power Green Beam Laser Pointer Pen (infrared filter), and im having an issue with the button on it. it was working fine, but then after use it started to be harder to turn on, and the button just stopped working after a while. do you guys have any ideas on how i can fix it?
