I live in a small town that looses power freqently. Sometimes we'll not have electricity for full days/nights. this little light is so much better than the basic flashlight because it's bright and uses no batteries. I have even read a book by this light, just crank it up and get on with it.
CAUTION: Leave the flashlight some place very handy so you remember to wind it up once a month or so. Failure to do so will damage the light beyond use.
Keep one in the car, kitchen and bath.....be safe!
