Coleman's new range of propane fuelled stoves has some real advantages over propane/butane mix stoves. Firstly, they are more efficient; second, they can be used in extreme temperatures; third, they use built-in regulators (no more singed eyebrows) for a steady fuel stream; four, the non-refillable propane cylinders are light, compact and easy to transport and lastly, the cylinders can be used for a full two days (based on 3 meals per day). The Perfect Flow 2 Burner features 2 fully adjustable burners, lid/windshield, side windshields, Instastart ignition. Ready to use with Coleman propane canister.
