I already own two of these - When the family goes skiing, we fire them up at the beginning of the day and they're still going strong long past when we're done with the slopes. The key is to fill them enough, but not too much... The measuring funnel thingy that comes with them is perfect for that job... After a few uses you'll get the hang of it.
Way better than the solid fuel or battery hand warmers, and way more cost effective than the disposable kind. If you do stuff in cold weather, these are great to have around!
