I have four mini-led maglite -lrb- three 2aa , 1 3aa -rrb- , two 3d lead maglite , one 2d lead maglite and a few non-led 3d\/4d maglite in various color . I use to buy nothing but MAGLITE flashlight . however , unlike the non-led maglite , the more expensive -lrb- minus -rrb- lead version have all-but-one fail over time . I have not have much trouble with the bigger light , especially the non-led version . all but one of the mini-maglite led flashlight that I have have develop weak connection or corrosion after a year or more . I start see the light go off randomly while use it . shake it help for a while , but eventually I be smack it on thing to get it to come back on . after a while , I give up . the battery do not seem to drain evenly , one battery can drain to the point that it leak all over the inside of the light , while the other be still over 90 % capacity . happen more than I like . the only mini-maglite that still work for I - I have to pry out a battery from it today . mag research probably have great customer service , and they 'll remove leak battery for you , fix stuff if you send they the light . but for something $ 20 or less , it be not worth it for I . I just throw it in a part drawer in case the one mini-maglite I have leave need a spring or something .
