Mediocre lens for its price, after some, maybe several, falls (I've been using it for 2 months) it started trembling to the point where it needs a hit to start working again, like all metal lenses do, and the intensity decreases as if it needs to be charged but after a few opens and closes it comes back. Battery life easily lasts 3 days, I would prefer it to have a tape-type charger instead of the small pin for charging. Good intensity for non-explosive use. The build quality is the best I have seen, the button of the Phoenix easily plays to be the best of all.
