I be give this light by my brother and it work great . the casing be very strong and duriable , and the flashlight be very bright for it be small size . you can still even see the beam in a well light room .  the only reason I be bother to put in a review be to give a word of warning . while deffinately better than any other flashlight of this size I have have , the on\/off switching method be not perfect . the regular maglight be say to have superior switch that do not fail as be so common with a regular flashlight . however the double a battery mag have a different type of on\/off switch . with this type of switch you screw the head in or out to turn the light on . this switching method be not perfect because you also adjust the focus of the beam with by twist the head as well .  the problem my little mag have be that at the tightest focus , the head be rather loose on the casing and can rock back and forth . this rock can cause the flashlight to shut on and off when the head push against the off switch\/lighting assembly . most of the time when I be use a flashlight , I want the strongest beam\/tightest focus , and it can be a bit bothersome to jiggle the head so the light remain on .  this thing be still better than any other minus flashlight I have ever see , but I just want to let those of you look know that it be still not perfect .  I would recomend you get one anyway .
