I have own and use mag light for year they be very reliable and put out great light . I love the way the beam on the flashlight be adjustable , you can zoom in or zoom out with ease . it let you see whatever you want with bright light . Heavy enough to be a very good weapon in a pinch . this one we keep here at the house for emergency power outage , or to look around outside at night . they be great to have around for this purpose . I also purchase the hanger to attach it to the wall in the garage . very easy to install and let you place it in a handy spot so you can get to it when you need it . we have several around the house . they always work replace the battery once a year , more often if you use it a lot . it will work for year .
