Zippo Hand heater is ideal shot for me and super effective! I'm really satisfied with my purchase.
Lit at 7.30am, he extinguishes approximately 18:45 with a full (about 12 ml).
And with a full half, I turned to 19h and it extinguishes toward 0h!
It heats very well, and we can "choose" a little intensity by adjusting the opening / closing of the cover.
To turn off along the way, simply remove the burner with the cover and wait for it to cool like that, no waste !!!
For chilly: to buy again!
