Original did not function replacement was perfect - LaserMax CenterFire Gripsense Light & Laser

I ordered this as opposed to the Crimson Trace brand due to not wanting a button to have to press, the Lasermax unit with GripSense is fantastic. It also mounts a lot more sturdy to the trigger guard, there is no way this thing is coming off under normal use. The green laser has a huge, easy to see dot and the light is more than adequate for basic use after identifying your target with a primary flashlight.
The only issue I had was that the one Optics Planet sent didn't have a functional light, I called Lasermax and they were spectacular, sent me one within 8 business days, especially amazing being that it was between Christmas and New Years, and the unit worked perfect. The laser could not be easier to pickup in any lighting that I could try.
