What if my light could open a bottle? Done. Introducing, MicroBrew, the key chain "tool" that lights up the cooler and opens the brew! Replaceable battery, powerful L.E.D. available in white or red. Beer anyone?
Great light, I start work at 5am and winter can be pretty dark, really helps. Bad thing is I turn it on in my pocket alot and the batteries cost as much as the light.
