have read the other review , I decide to add one myself :  many police department standard issue mag Lite product . the 2,3 . . etc d size flashlight make reliable flashlight and they weight can also make they useful as a baton in a pinch . I have several different mag light -lrb- the minus 's , the 2 , and a 5 d monster -rrb- . they always work , the beam be generally good , and for the money , they be a good value . they be not the best flashlight ever make ... but for 20-30-40 buck , they be a great flashlight for about 99 % of what people need flashlight for ...  if you really need alot of quick light - i.e. , you be plan to rely on this light for a tactical or self-defense situation , then I would not buy a mag Lite ... ASP , Surefire -lrb- my favorite -rrb- , Inova , etc. , make much better flashlight for that situation . a surefire c2 or z2 model be about the size of a Mini-Mag but deliver about 5 time the light of the largest mag lite product ... all without a focusable beam . the technology of SureFire be unparallelled , in my opine , but I think it be akin to compare a Ferarri to a Ford ... yeah , they be both car , but that be about as far as the comparison should go ... also , most high-performance flashlight run for about a hour or so ... mag 's will run longer . also , you can go to any hd or hardware store and buy mag , battery , lamp , etc. ... try do that with a SureFire ... NOT . so there be comparative advantage and disadvantage to both ...  mag 's product be good ... but you get what you pay for and not every flashlight be suitable for every application . if you be a LE officer , military , etc. , it be unlikely you will want mag Lite as the product you be go to trust you life to ... they just be not bright enough to stun someone in a life and death situation ... if you want a decent reliable flashlight for home emergency use , then mag lite be the best product you can possibly buy .  ... I own both for different reason ... I just wish I own a Ford and a Ferarri too !
