Pros
  • No air controls to set: it adjusts the burn on its own
  • Only 16 in wide, so it fits small rooms and tight spots
  • Cooking surface on the top plate
  • Heats with no electricity, so it keeps working in a power cut
Cons
  • Lower efficiency (71%) and higher emissions than catalytic stoves
  • Small 1.25 cu ft firebox limits burn time to about 10 hours
  • No manual control, so you cannot turn the fire down yourself
