I gave the can to my parents. The build quality is top. And it really works well! We recently grilled with the whole family. And the sausages and steaks were really a long time wonderful hot / warm in the can. Thus, also the grill master eat with alone when he "prepared the" does and does not have to constantly be on the supply at the BBQ.
The trick is simple in principle of two nested cans. You also can use individually. Both have their own cover.
