Laundry won. "My bad" as they said in the 90s. Not sure if it was me or my 6 yr old that left the light in a pocket of pants that went through the wash. Only found it in the drum of the dryer. I tried the trick of sealing it up with rice to dry it out, but no luck, the light just makes a buzzing noise rather than light up when you put a battery in. The light is not marketed as waterproof, so it's certainly not a design flaw or anything. I have already ordered another, I really miss having such a small, bright light always at hand.
