Cheapo LED Flashlights --- Battery Hogs?

I have a bunch of the cheapies... and usually most just don't work, so I just toss them in a bin. I hate to trash them because they are CNC machined aluminum, so I gut them, toss the innards, then recycle the outer case and the endcap. You get what you pay for, and so far, I've found that the Coleman and the Smith & Wesson flashlights will not just be bright, but actually turn on when they are needed. You do pay dearly for them, but made in USA usually means it will work and work right.
