Easy to use and works well with tyhe table top furnace that we received from Wayfair. The fuel lasts for quite sometime. If you only add what you plan to use. I would recommend to not fill the fuel resevoir if you only plan to use the furnace for a short time. Otherwise you waste the fuel. Since it does evaporate when not in use. I am happy with this fuel product. It is hard to find at local hardware stores.
