Don't buy it! It's A blatant ripoff of Fritz's Bushbuddy stove which has been around for a number of years. Fritz is a small cottage manufacturer and can't afford to pay for patent protection from large manufacturers. Fritz's stove is half the weight and has a more robust build. Check out numerous comparison vids on You Tube.
Mitchell11I would love to support Bushbuddy but as someone else pointed out the stove is $100. If I am going to pay that much I would need to see the patent you mentioned. Please provide the number. As fas as I am aware wood gasification has been around since the 17th century. Germany used it in cars for WWII.
