I own about 4 or 5 of these little light and they be great . they easily fit into glove compartment , tool box , even you pocket and be always handy . my 2.5 year old son be fascinate with my flashlight and so I buy he a `` cheap '' immitation , which quickly break . I replace it with another and it , too , break . I find they to be unrepairable . I then decide to get he he own mag light . not only do he love it -- it be the first thing he ask for in the morning these day , but it be repairable . he have drop it and try to take it apart many time . usually the drop either break the bulb or dent the top contact on the battery -lrb- which need immediate replacement . -rrb- one time it just be not work after replace the bulb and battery . I almost give up when I decide to take apart the plastic ring that hold the bulb -lrb- it actually say `` do not remove '' -rrb- I be surprise to find how easily it come out to expose the contact . the contact that touch the housing that turn the light on and off be slightly corroded\/gunked up . I clean it lightly with steel wool and snap it back together and it work ! all in all , a handy , rugged , and repairable little light !  buy several .
