Having a magnetic flashlight is indeed handy - especially for a mechanic. My husband is an aviation mechanic and he loves that this flashlight provides him a source of light and both free hands.
Hidden in the handle of the flashlight is a lantern. All you do is pull both ends of the flashlight and the lantern becomes visible. It provides a low lamp-style light, which is ideal for camping situations or when the lights go out. And since it is magnetic, you will be able to stick that emergency light on any magnetic surface and be assured that it will stay there. You will not have to hold onto that emergency source of light.
There are two downfalls to this flashlight, however. One - it uses four AAA batteries. In my experience, AAA batteries are more expensive than AA's. Also, the flashlight does not offer any options of brightness. The option is does provide is low, but that is not necessarily a bad thing. If you do not want a blinding source of light in the dark, this might be just the ideal flashlight for you.
