I have never used it. It was bought at a swap meet in CA 10+ years ago just because it was so nice, it still has the orginal globe with the sunburst on it. oh and I only gave 5 dollars for it.
I have one I bought 15 years ago that runs on coleman fuel or unlead gas.
I also have a few older ones that are just for looks, don't use them. One of them rums on some sort of butane canister.
