I just recently picked up the Innokin MVP 3.0 Pro starter kit, it came with the mvp 3 mod, a Isub G tank, 1 coil. I noticed that it tastes semi burnt (the vapor) and it destroys my throat, it hurts really badly. Almost as if it burning really badly, however, my tongue, mouth etc feel absolutley fine. It causes me to cough and drink water or elese it is unbearable. I have used other vapes with 12mg nicotine and its no problem, this however is 0mg. a 50/50 pg vg grape flavor, and a 70/40pg vg. I am unsure if it just needs breaking in, if its the vapor or what. I was FINE with my friends vape pen, 0mg no burn at all really really smooth and i loved it. I dont even want to vape anymore.
