I have have my mag 2 d-cell flashlight for over 10 year now , and it still work flawlessly . while other flashlight have rot , rust , or just plain break , my mag still shine . it be literally the last flashlight you 'll need to buy .  the fact that you can adjust the beam from a broad floodlight to a focused spotlight be nice , though I have find that mine do not focus into a small , even circle as well as I would like .
