Good unit so far - - after only 30 rounds. - LaserMax CenterFire Green Laser Sight for Ruger LC9, LC9S, and LC380

Pros: Green works for me with regard to visibility. Small, clearly defined spot, actually is visible on many daylight items if not in direct sunlight,(pleasant surprise) mounts in minutes with slight glitch, easy to adjust. Mine is dead on at about twenty feet after tweaking, has not moved after about thirty rounds.
Cons: Ugly, reduces grip length by only about 1/8th of an inch but it is enough to get my pinky hanging off the edge, lacks auto shut off, drilled out improperly to accept screws.(When joining two pieces the first piece should be drilled to clear the threads, the second piece should be drilled so as to engage the threads. They used one drill so that both pieces engage the threads. Attsa no no. One must either drill out the first piece to clear the threads OR clamp the pieces together VERY FIRMLY or they will not snug up. Did I mention ugly? Would I purchase it again knowing what I know now? Yes.
