Yeah, I almost burned my eye out using that stuff. It sparked and popped really bad. One big pop sent a hot piece right at my eye. Luckily I closed it and only burned my eyelid. Other than that it seemed ok!
Yea I know what you mean I have used several types of lump but none with this much sparking. Cooks ok not a lot of unburrned left I mainly use lump for grilling but will use it in the smoker with no complaints.
