I purchase this tactical flashlight for my dad. He said that it is a compact, lightweight, military gradeable whatever that mean best flashlight he ever seen. You can use the bottom as a hammer in an emergency situation. It also come with a rechargebale battery. The neat thing is that it comes with a charger so you can charge it at home or anyone's car. The light is so illuninated that you can even zoom in or out. It is so bright. Don't worry there is three stage of low, medium and high brightness so you are not just stuck with one setting. Overall, this is really a nice tactical flashlight that come in a very nice case. I am glad I purchase this for my father.
