I have a bag of USA and several bags of Mexico. The USA bag is much larger even though it's the same weight, like a bag of potato chips, lots of air. I haven't cracked into either one but will report the results soon. I heard from a friend that bought from the same pallet that the stuff from Mexico starts with a bad smell almost like plastic and burns pretty fast. Like everyone here I'm giving them another chance based on what other people are reporting in this forum, fingers crossed.
