The deer caught the scent and my husband decided not to use it

Otherwise, keeps hands warm for a long time! Keeps my hands warm without fail

I fill it every morning before I leave the house takes less then a minute to fill and if you want to really be stickler for rules it takes 2-3 minutes to properly prepare it based on instructions, but honestly extra time only comes into play if you overfill or spill, if not less then a minute and your on your way

Wait a couple of minutes for all fumes to dissipate and put away your can of lighter fluid, clean up any spills, etc

It doesn't make a visible flame, so you may need to wait a few seconds or even minutes to be sure it is lighted

It's not difficult or in my opinion dangerous but DISCLAIMER I only do this if its truly necessary to turn it off, I have a safe place to do it, and the time to wait and supervise while the cooling happens (Usually 5 minutes)
