I have not seen a lot of posters here that use the chips with the MES 30. The most traffic I see on this board are MES owners who use the
AMNPS pellet tray and burn food grade wood pellets instead of chips. I am pretty new to the MES and smoking and have never used the chips. I've only used the
AMNPS and have not had any of the acrid smoke. Some of the more experienced smokers should be along to help. But here is the link to the pellet tray if you are interested.
