So just got a mouthful of horrible acrid burnt taste assumed the coil has gone remove the coil then pull it out to just look and the Wick looks fine and the coil seems fine.. i only bought it yesterday .. i am only at 15-20 watts. .. it's the Kangertech tank.. so i have a spare coil and it's 15-60 watt coil so I put it in and fire it up but it's just not the same vape.. it's difficult to get a good vape I have it on 25 watts.. my question is how long should the first coil have lasted and does anyone have any suggestions on the second coil not performing as well..
