these little flashlight rock . I must be the last person in the US to discover Mag Instrument flashlight , but I be a solid convert now .  when you be camp , especially backpacking , a little light like this be very handy . the battery do not last long , but they do not weigh much either -- a key factor for backpacker . and they be very rugged . I live in a wooded suburb at the end of a country road -lrb- at least it use to be a country road -rrb- with frequent power problem . we must own 10 flashlight already , but be replace they with more reliable unit -- like these little mag light .  we buy the accessory kit with the lanyard -lrb- and other stuff that we find less useful -rrb- . for camping , we also buy a non-mag belt holster that can hold both the light and a knife or Leatherman .  highly recommend .
