I buy a 2 aa Mini LED . the first one last about a week . it start flicker just like the two guy mention in there review . it be useless now . I wait to long to return to lowe . so a few month past before I get around to deal with the problem . I purchase the same exact light from Home depot in a town a hour and half away . I be sure you can guess what I have plan . to my amazement the replacement never work out the box . just do the flickering thing . I be not a review writer type of of guy , but this have get I boil over . I like mag lite just not the lead 's . do you self a favor and stay clear of this piece of garbage !
