Overall this light is a very good product. It is built well and the mount is very nice. The pressure switch has also worked well, but a constant on switch would be nice. If I had the purchase to do over again, I would have gotten a model with the LED bulb. This is a good product, but you get what you pay for. I have a streamlight TLR on my pistol and it is much better light than this. Some reviews say that there is no difference, but there is. If you want surefire/streamlight you have to pay for it. If you want a quality weapon light for 40 dollars, then this is what you need to go for.
Pros: Inexpensive, quality product, adequate brightness
Cons: No constant on switch
