I bought two, one did not work. The compony response is pending. I like the one that works. UPDATE - Here is a company that cares about the customer, when they arrived, one didn’t work I am really happy and impressed with the speed of GearLight’s resolution. Nathaniel Newman, the customer service manager, sent a personal note to me, along with TWO replacement flashlights AND batteries. Thanks so much for that, I’m knocked out. These flashlights are compact, they fit right in your hand, and they widen the beam by extending the front part. It has different modes, including a strobe for self defense. They are really bright and that beam widens out quite a bit, the specifics are on the site. I am very happy with these lights and I now have an extra for a stocking stuffer! Thanks so much for a great product and fantastic customer service.
