Things I liked:Good construction, nice beam, solid mount, good focus ring. Things I would have changed:Battery life, but there's no getting around the fact that light requires energy. Somewhat of a short range, but it gets the job done. What others should know:I expected little from this light given its price. I was happily disappointed. It functions well, but it can be taxing on the batteries ( an inescapable evil of non-LED tactical lights ). I work on a cattle ranch and this light comes in incredibly handy for dealing with predators. You get a lot for a little with this item.
