after have several other led flashlight all I can say be this one take the prize , and be the best I have find . it have all the battery and light life that you would expect from this technology with the build and focus-ability you would expect from mag . most other led flashlight be only good for close range situation , while this one do both close range and long range thanks to mag 's twist focus capability . so get this one , even if it be a couple of buck more . it be also nice that it be make in the USA .
