I bought a pink one for my wife's pink LCP and it has been working well (only about 100 rounds). Based on that one, I purchased another for my pistol. However, the first two did not work on the pistol. The first one quit working after about 50 rounds, so I returned it. With the second, I could get the laser to come on when it was off the gun; but, after installing it (before even shooting) it wouldn't work... the only way the laser would come on is when it wasn't installed. I have sent this one back and am waiting for the third one, which I hope is a charm...
Pros: Ease of use
Cons: Poor quality control
