have this flashlight for a while , use it only a couple of time and when I need to use it today it would turn on and flicker off when I tilted it . replace the battery and now it will not event turn on . be able to get it to turn on for a couple of second by adjust the battery cap , but will not stay it on , and I never even drop it or abuse it like I do with the old incandescent aa maglite . then after read the warranty I find out that the led be not cover so if the bulb burn out , you be leave with a useless aluminum battery holder . not on par with the Maglite tradition .
