Very nice
It's a nice hand warmer. The build quality is very good, even the little bag is well made. And its nice and warm when it's going properly. However, l find that the heat output is not very consistent even though l use good quality fuel. If you take it out your pocket and hold it in your hands the it will cool down very fast until it's barely noticeable. And if you put it down on a cold surface like metal it will go out completely in a few minutes. There is definitely a learning curve to using these warmers. I also have the whitby warmer and I find It to be much more reliable and it burns much hotter and its cheaper, but the build quality is not as good as the zippo. The zippo feels very good in the hand and has no sharp edges but the whitby does. And the whitby will still go out if placed on a very cold surface, I guess all warmers do that so be careful. So if you're more concerned about looks and feel then I would recommend the zippo. If its more heat and reliability you want then get the whitby.
