I have slog through my life use one crappy flashlight after another . finally , after I lose power at my house for 3 day , I say enough be enough and purchase this flashlight . it be simply amazing . solidly construct . incredibly bright . Worth every penny . Update : well , my feeling about this product be not so rosy anymore . after about 1.5 year of own this flashlight , it stop work . I open the battery case and discover that the battery be leak . I check the warranty and although the flashlight have a lifetime warranty , the battery do not -lrb- it be cover for only 1 year -rrb- . understandable , but it be unfortunate it last less than 2 year and it be $ 20 for a new one .
