Purchased this weapon-light 8 months ago. It's fantastic for low-light and night-time hunting of hogs. Attaches on to Picatinny rail and locks into place with ease. The product sheet says that the light will last 1.5 hours of continuous use, but I've used it intermittently for months and have yet to replace the batteries. I don't use the navigation lights, but the main light is very bright and lights up a large area at a distance - allowing me to use my red-dot to take the game easily. Would highly recommend this product to anyone on the fence about it. It's high-quality and lightweight to boot.
Pros: Easy to use, great for hog-hunting
