I received the Bright LED Tactical Flashlight TK120 free of charge for my honest review. The Bright LED Tactical Flashlight TK120 can work on either three AAA batteries or one 18650 Lithium Battery neither kind of batteries are supplied you must purchase your own. I had the batteries so I installed them and the Flashlight worked great. The Flashlight is small lightweight and the zoom pulls out and it is the perfect size to carry in your purse or pocket and it has a wrist strap. The zoom really works great from small to large size light. The aluminum edge of the Flashlight is tuff enough to be considered tactical for self defense you could strike a person in the nose with it and run. The Flashlight has five modes and a memory mode, high, medium, low, strobe, and sos. I highly recommend the Bright LED Tactical Flashlight TK120 that can be purchased on amazon the link is below and you can also purchase the Flashlight in a complete kit. Thank you, Jerri
