pro : it be fairly bright in the 100 % . the candle mode be sort of useful when work on something in the pitch black and you need both hand . con : the lead housing seem rather poorly place inside the tube , when work on a car and if you tap the flashlight on anything it will switch mode on you into S.O.S. mode -lrb- it blink in morse code -rrb- and it seem to happen quite often . overall for just a normal flashlight to use when walk around in the dark or look through storage it be decent , but if you be do anything that involve a lot of movement or tight quarter I would recommend a different flashlight . I end up give this one away and buy the  fenix e21 flashlight
