I recently purchased the Ranger model and used it this past weekend. It burned so efficiently, and threw an amazing amount of heat with much less wood than a traditional campfire. Only a little smoke when first lit, once warmed up, zero smoke!!!! I'd initially ordered the Bonfire, but found it larger that what I was looking for. Not Solo's fault, but they sent me a return label so I could exchange it... No questions asked. Love this stove and the fantastic customer service!! Highly recommend!!!!
