purchase this small led flashlight to try out for a all around toolbox , glovebox , field inspection light . I currently own two original 2d cell maglite and they be excellent , both 5-6 year old and great shape . I purchase the genuine Maglite LED upgrade kit for both of they and be very satisfied . Have have the same d battery in they for 1-2 year and they be still put out great light , so excellent battery life . for the small 2aa light , first the pro : the aluminum housing be solid , same quality as older maglite ; the lead light be actually brighter than my 2d lead maglite and i actually prefer the 2aa light as it be whiter , and if the control work well i would buy more of they ; the size be perfect . for the con : the control make this a very annoying product ; the twist on\/off be fine , but one small bump or a small twist of the front and it shift from high to low or to flash mode . twist control fine , but when you pick 100 % on it should stay that way unless you intentionally change it , not change with a mild touch . when inspect a building with colleague the last thing I want be a flashlight to start flash like poltergeist . I personally would prefer just on\/off , or on 100 % \/ on 50 % \/ off . the flash light and SOS mode for I be unneeded ; the 25 % mode be too dim to be useful , i would recommend 100 % \/ 50 % ; nextly , the end battery cap do not stay on tightly . my old maglite have to turn hard to tighten and they stay that way . this battery cap loosen easily and then actually switch the mode -lrb- 100 % to 25 % to flash -rrb- when it be loose ; lastly , i do miss the on\/off switch find on the 2d light . final word : frame quality , great . brightness , great . just need the old Maglite rock solid on\/off control . user tip : I actually put some white teflon plumber tape inside the thread of the battery cap and it stay much tighter . I also put teflon on the inside on\/off thread and it be harder to twist , so it do not switch mode by itself so easily . not sure how long it will last but worth a try .
