I have purchase maglight for over 30 year , but the 2 I bouhgt here recently be pure garbage . both , within a matter of day , lose the button cover , both swell up with new , expensive battery and would not work . I be qualify to state this because I have a radio Amatuer , EXTRA class , ke5ldo , for many year , and this have never happen before even in the hot sun ! because they be inside a air condition room I would not expect either problem to happen . I save the bulb , end cap , and the hood in case I be ever givien one . I will not be buy they again !
