The "Ranger Solo stove" is awesome. It starts the fire quickly and burns efficiently. In the beginning there is some smoke but that goes away in about 10 to 15mins after ignition. I use alittle fire starter cube to get it going. 3 bundle of hard wood should last most of the night. (Burn for about 6 hours) Heat output isn't the greatest because all the heat is projected upward but good enough. Cooked some marshmallow to make Smores, and Spam just because. The thing is great. Constructuon so far looks solid and well built. I wonder if they're going to offer some sort of lid to extinguish the fire or a cooking rack system. So far we like it and it'll be a part of our camping gear we will take on our trips.
