Simple to operate, a sturdy stove suitable for all temperate outdoor activities. It's convenient, just light it and cook, no pumping required, and it simmers precisely. LPG stoves do not function well at below-zero temperatures at low or medium altitudes, since the pressure inside LPG cartridges is reduced by the cold. At very high altitudes, the lower ambient air pressure helps offset the reduced internal cartridge pressure and improves sub-zero performance
