I really like the different settings of laser, light or laser/light combinations, brightness of both lights and the ability to see the green laser on daytime targets. Metal rail mounts might be a nice addition but would definitely drive up cost of an already great product. Have tried the other two big name companies that now offer green lasers but still prefer Viridian. I have three including one with remote switch for rifle/shotgun use.
Pros: fit, looks, easy to use, selection of light combos
Cons: none
