I liked my first one so much I have two.  One is on a .40 SW carbine.  The other is on a 30 carbine rifle.  Both are reliable and accurate.  I don't use the laser past 25 yards because it's difficult to see and IMHO laser if for close quarter work and quick target acquisition.  I've used the green dot for shots out to 100 yards but realistically go to an offset scope at 100 yards.  
Pros: Works as intended and is very accurate
Cons: green dot on as crisp as I would like
