This is not the smoke you are used to. The EG18X has 140g of composition, and the SD75 has 503g of composition. You can do the math on that. No need to double up with this badboy. It’s also not small. Probably the size of a 1L bottle. But damn is it a lot of smoke. 90 second burn time. This is the highest output “cool” burning smoke. Even more output than the military grade.
