Beamshot, give it a shot - Beamshot Green Laser Sight

No complaints here. I also run Streamlight 8 AG Flex and Surefire 300. Is it as high of quality as those? No, however for the price you cant complain. No issues with function, mounting, or buttons. I do like that each button has an led indicator of what function you have set on the two paddles. Not the brightest light. I was surprised in the performance of the green laser. If you're on a budget this would be my recommendation. 400-500 rounds of .40S&W and it still functions perfectly with no hiccups.
