I have use this flashlight in Haiti , in the high humidity and extreme dust . it hold up beautifully and I always leave mine behind for friend to use . I now use maglite 4 and 6 d cell flashlight at home and in the car . they be easy to grip , easy to focus and solid . plus they be MADE in the USA . something I have recently come to pay attention to once again . when I be a kid , we always look for the union label and make in the USA marking and somehow slip away from pay attention to that distinction . this be a well make and hardwork solid tool well deserving of the accolade it receive .
