I just purchased 10 bags of these pellets to see how they burn. I was pleasantly surprised that these pellets burn extremely hot and have no more ash than other premium pellets. Considering these are local and are cheaper than other pellets I plan on buying more. I will say that the pellets have a distinct smell from other hardwood pellets that I have used. The material used to make these pellets are described as "Wood" on the bag so they might have some softwood or be all softwood. Either way I recommend these pellets.
