I just bought a whole bunch (like 40) of really cheap, 2-D cell flashlights for work, and I cringed at first, but then I started thinking. I can't really justify purchasing "what if" emergency flashlights that were 15-25 dollars each. Cheap-O 2 d-cell plastic lights that you can keep a whole boat load around, in case of a power outage, or hurricane or flood, you can hand these out to anyone who needs them.
I guess in this case, it's quanity not qualitity.
Of course that is NOT what I keep in my desk!
You keep these around in case of emergencies, if you have an emergency, you hand them out, and never worry about getting them back, and instead of handing out a couple of precious "good" lights, everyone gets a light in an emergency.
