Using the UCO Foldable Flatpack Smokeless Firepit & Grill is a breeze. First, unfold the firepit in about 30 seconds. You can put standard 16” cordwood in the spacious firebox. Once the fire is lit, enjoy the smokeless experience as the double - wall design burns off the smoke. If you want to use it as a grill, simply insert the included grill grate. When you're done, break it down in 30 seconds and fold it to less than 2.5” thick, then put it in the canvas carry case for easy storage and transport. As for maintenance, since it's made of stainless - steel, it has good rust and corrosion resistance. But it's still a good idea to keep it dry when not in use. Also, make sure to use it in a safe, above - ground area to avoid any fire hazards.
