Folks, I am into my 6th heating season using wood pellets, but this is my 1st year using your pellets. I am extremely happy with your product for the following reasons: 1. Way more heat output 2. Ash content is half of what I am used to 3. No sawdust in your bags 4. Window film build-up is less and wipes off with a damp cloth. In the past I had to use an abrasive cleaner to remove film. What ever your manufacturing process is, do not change it. You have the other pellet manufacturers beat by a mile.
