its a maglite . its a tough little bugger , and it will outlast all you other plastic flashlight . one problem be the bulb be not very bright . they be good candidate for led replacement . one problem I have find be that the battery tube be just large enough for 1600mah nimh aa cell , but the larger capacity cell of 2000-2650mah be too `` fat '' and will not slide in . alkaline will work well of course , they be skinnier . like other maglite you can take off the focuser and use it as a `` candle '' . the tiny skinny bulb be fragile so it will not take much abuse . its pretty heavy despite its size so you may have problem hold it in you tooth of you want to use it `` handsfree '' . the rear cap have a hole for a lanyard strap and I suggest you use one , cylindrical flashlight have a bad habit of roll away at inopportune time .
