I just got this kit 2 days ago. The realeaux rx2/3 with 3 batteries in it. I poured 18mg nicotine juice inside, and gave it a shot. It burnt my lungs very badly at any watt and voltage. I tried it today, with 3 mg nicotine juice instead of the 18. Doesn't burn anymore, But it tastes revolting. Idk what to do, I just bought everything brand new. The coil can't be ur t out all ready?! I would love some advice as to what to do, I'm a newbee to vaping. What is the problem? Thanks.
