Query: Simple, sturdy, efficient

Title says it all.No bells and whistles. Just a simple wind up lantern. Decent construction. Small enough to pack. Lights up a room enough to do basic tasks. Bright enough to read by if set next to a book. More efficient than the others I've used over the years. A minute or 2 of winding gives me an hour of light.What happened after Katrina should make it obvious to everyone that the potential for long term power outages is a reality. Batteries and lantern fuel don't last forever and this is light on demand long after those burn out. The ability to light the darkness is important for both physical and psychological survival. Every home should have at least 1. With this you never discover dead batteries at the wrong time.Delivers as advertised. Nothing more, nothing less. I can't give it anything short of 5 stars.
