“If u smoke a lot of crumble or crystaly diamonds this is the way to go! 20 outta 10 for sure! But for a fair warning cause I've done this a few times before I figured out what was happening. DO NOT put sauce or any of the wetter, gooey, rosin in this coil. It'll smoke it but it'll be messy and won't work to well. It also shortens the life of the coil by getting places the other stuff don't and burning since u can't clean that area or even know it's dirty, for that stuff use the QDC coils like the pen itself came with.”
“The quality cannot be beat because you can soak the quartz coils in cleaner and just reuse. They will not look brand new. But they will definitely work again after cleaning. I've had the same 2 coils for over 6 months.”
