Just didn't care for them. I know a lot of people like them, but when I used them for even a shoulder pellet I didn't like the heat. It's not that they burned bad or gave a bunch of clinkers, but it comes down to heat for me which is why I bought the stove in the first place. Yeah they burned in the Harman, but others burn better for me. I actually loved the Presto logs which are very close in price and readily available to me. Putting the 2 side by side I'll take the Prestos 10 out of 10 times.
