when my husband receive this as a gift ... I promptly steal it from he . it be nice and light and you can keep it in you purse or in the glove box in the car . if you headlight go out you could use it to drive by ... just kidding . the light output be very impressive . I like this size since the larger 4 and 5 battery size be very heavy . I wish they would dream up something besides the diamond-knurled grip . it give I the same feeling as chalk scrap on a chalkboard do ! ~ the Rebecca Review
