This stove still continues to impress me. Loaded it up with Poplar(lombardy?) this morning at 7am and it's still going strong at almost 9:30pm.(stove top @350*) Daytime temps "might" have touched 40* for a minute. It's about to get warm in here since I turned it up a little in order to make room for reloading tonight. The last few days I've been burning a poplar/oak mix and getting 22-24 hours with ease.
