So i got an i clear 30 a few weeks ago from okc vaes norman vapes location and i loved it but for the past few days it has been gurgling, not producing much vapor and the throat hit is so harsh it has me coughing like crazy , ive replaced the heads multiple times, disassembled it cleaned and reassembled it several times and i cant figure out what is going on , ive even tried several liquids, i made a thinner 80/20 same thing, tried a thicker liquid at 50/50, same thing! i am stumped?!?!
