I'm a dedicated Zippo user. I've got three right now. I've never gotten one wet enough to kill it. I go a week on a fill at two packs a day, a month os so on a flint. The only think I've ever had go really wrong was to mangle one enough that I had to put the top in a vise to get the sleave off it. That one went back to the factory, and came back better than new -- for free. All they asked was for me to tell them how it happened.
