this lite be better than many other flash lite because of the switch ! -lrb- twist switch -rrb- . i get mine about 6 year ogo and use it alot !!! very heavy use ! its be turn on and off hundred of time and still work great ! i do have battery leak in it before they be dead ? do not know why they leak ? it have be drop many time . i do have to clean the switch from dirt and the leak battery . there be 2 way to clean the switch . first way be easy . you just turn off the reflector = candle mode . then you twist the top part that have the bulb in it . with the battery in will clean it most of the time . pressure from the spring push up on the battery make the switch contact . if that do not get it clean then what i do be take the battery out and remove the bulb then carefully pry up the bulb holder on both side at a 180 degree angle . it have 2 plastic post that friction fit . once apart clean the connector and underside lip so it will make contact . i have do this 2 time and reassemble with no problem . even flash lite that cost 10 time or more may not last like this minus mag because of the switch wear out or get dirty and not make contact . but most switch i see you can not clean they they do not come apart . also they be a different kind ot switch . i put in the 3 lead bulb and love it . battery last longer and it be a white lite . i have a $ 50.00 lead lite that be nice but allready after turn it on and off about 75 time i notice it be start to get worn . once and a while i have to push it 2 time to get it to come on . if you want a lite that will last this be the one !!!
