The hottest one
Very good warmer that burns nice and hot and consistent. And the refuelling gasket is a much much better design than the competition. A couple things to note though, if you drop it the burner will come off and it will go out immediately so always bring plenty of fire to get it going again. Secondly don't put it down on a very cold surface because the loss of heat will make it go out in a few minutes. And if you interrupt the burn halfway through the cycle it's quite hard to get it going again. I have the zippo warmer as well and the build quality is much better than the whitby, however the whitby is cheaper, burns much hotter and is much more reliable than the zippo warmer. If you want the looks get the zippo. If you want the performance get the whitby.
