I have own at least 5 maglite and especially like the minus mag but with all of the maglite I have have the same problem : suddenly they do not work . when I take the battery out and put new one in , they still do not work . if I change the bulb they still do not work . it seem that they be very touchy about the way they be put back together . they have to have the spring situate just right among other thing . I can not believe that other people do not have the same problem I do . my boyfriend just spend 30 minute cursing , try to replace battery and\/or bulb without any luck . we now have 3 Maglites sit around as piece of art rather than useful illuminating item . help ! what be we do wrong ?
