I have several of these Mini MagLites . they be solid , well-made , great little flashlight , with extra feature : beam focus -lrb- just twist the head -rrb- , spare bulb holder -lrb- inside the rear cap -rrb- , and a candle mode -lrb- take the head off and it become a base for the barrel -rrb- . I have only have one fail , and that be my fault -lrb- I do not check the battery in one that be keep in a drawer and a expire battery leak -rrb- . why do I own several of these ? well , you have get to have one in each color , right ? seriously ... I keep one in the center console of my car . it be great for old eye look at a map or direction at night , when the dome light just be not quite enough . it be also a help for a quick look under the hood , in the trunk , or under the seat . of course , I keep a regular Mag-Lite in the trunk , too . I keep one in my office desk in case of a power outage , or when the time light go off in the evening , or for digging around in the computer or copier . I keep one by my home computer for those time when you have to go poke around inside . I keep one in the headboard of my bed , again in case of a power outage . I learn my lesson in the 1994 Northridge earthquake ; it be still dark and the power be out , and various and sundry thing have fall on the floor -- it be no fun walk around in the dark with bare foot when there be lot of stuff scatter about . there be a couple of other -lrb- kitchen and garage -rrb- , just to have around . just remember to check the battery every few month , and when the bulb burn out and you use the spare in the rear cap , replace it before you forget -lrb-  mag instrument lm2a001 replacement lamp for AA Mini MagLite , 2-pack
