This topic makes me curious - we bought a Harman and four tons of Freedom Fuel four years ago, then a tornado went through the neighborhood which gave us enough firewood for three years. We started using the Harman this year and the four-year old Freedom Fuel hasn't given us any problems. Because I've been reading about different pellets on this forum we sprung for $8+ for a bag of Lignetics from our local hardware store and found that they didn't generate as much heat as the Freedom Fuel. We did try some Maine pellets from Tractor Supply which we liked better than the Lignetics. I'm really curious b/c Freedom Fuel has such a bad reputation on this forum and Lignetics such a good one.
