well i have only used this once on my balcony so far, (see pictures), and i gave it one hell of a test, started burning coal on it at8pm. cooked a few plates worth of chicken, burgers, sausages and bacon. then decided to see if i could burn logs on it after, which it did rather well. burned thru a whole bag of open fire wood before running out and putting the rest of the coal on at about 4am then cooked more food when it had shrunk down enough to fit the grill back on. only needed the one side to cook enough food for 5 people so can imagine cooking a lot of food with both sides at once. feeling quiet confident about my next camping trip now as i really did keep it well stoaked all night to keep us all warm. also planning another BBQ/log fire on the balcony as it was good to watch a fire at home all night.
