I buy a couple of these to keep in the glove compartment of my car . here be why I like it : 1 . this take up little space -lrb- even in the include holster -rrb- and weigh very little since it run on two aa battery -lrb- which be include -rrb- . 2 . the beam of light be fully adjustable from a wide area to a spot with a simple twist . it be very powerful consider the size . 3 . this work great when you be look for something under the car seat , need to read a map at night , or need to check under you hood . Shop for price . I buy the exact same thing at my local Home Depot for under nine dollar , which be less than half the current price on Amazon .
