Crimson Trace products are well-designed and well-made. I have several CT lasers besides this one -- and they all work well. I had one CT laser for a new Ruger LCP which had a switch problem, and the CT people replaced the unit, with a very quick turn-around and free shipping.
Pros: I use primarily for dry-fire exercises, and the CT laser fits the gun well and is easy to adjust.
