In the extensive thread on HX pots, I sent Roger 2 pots, one of them I removed the fins and it's protective rim. I expected him to report back to the forum with his results but he never did. He created a pay to view article for BPL and never gave a thiought to add a comment in the thread to verify the 30% fuel savings using the HX pots.
Read the info on a post I made regarding the boil of 2 cups using 2 grams of fuel with the Etekcity stove and HX pot.
