I've gone
thru 10 so far. 1.7 ohms on just about any battery. Nice strong flavors and lot's of warm
vape. If ever you look down the center and don't see light at the end, blow them out from the thread side. Sometimes I'll also use some skinny copper wire and lightly poke from both ends. I condom fill them and sometimes the
juice builds up in the center pipe. They can last quite a while.
