I just picked up an Igo-L from a local vape shop about 2 hours ago, I've built 4 coils for it so far and every single time I get super harsh, burnt/dry taste that makes me cough up a lung and hurts my chest.. not to mention barely any vapor, its not even 1/100th of the vapor production I see others getting on RBAs and tastes absolutely terrible. I am so envious of people who get that kind of vapor production. I guess I just have no idea what I'm doing. I just use a small hex key, wrap about 5 wraps, hook it up and heat the coil to glowing for about 10 seconds, thread my wick and its always a terrible vape
