The 18” Original charcoal kettle is fuel efficient. I like that if I use large off brand briquettes then I can use them twice. I close up the vents to extinguish the fire when done cooking and have half of the briquettes I need next time. Half burned briquettes start faster too. A pot on the ash catcher tray makes it easy to dump ashes without having to scoop them out and dump the whole tray. A large piece of sheet metal 3’ x 3’ works perfectly to protect the wooden deck from burning embers. Don’t forget to keep a fire extinguisher around for good measure. Happy Grilling!
