Kool idea. didn't last long. - VISM Micro Greendot Laser Sight w/ Integrated Red Laser VDGRLB

I mounted this sight on a .22 Berreta NEOS handgun. I really enjoyed it for the first 500 rounds or so. Yesterday it wouldn't hold zero. When the front lens fell out, I understood why. The laser windage and elevation screws would vibrate out of zero from the beginning, which was no big deal, since I couldn't really use the laser in the daylight anyway, but I tried to fix the problem with some medium threadlock. I noticed recently that the plastic case on the laser split, presumably from the threadlock expanding on the threads of the set screw. I hope my experience is not typical, I'm still deciding whether to glue the lens back in, or pursue a warrantee repair, if I still qualify, that is.
Pros: Adjustable intensity allows you to compensate for lighting conditions
Cons: Front reflex optic fell out of the sight. Laser housing is plastic, set screws wouldn't hold zero.
