Hi, I thought I'd try a 2mm coil in my igo l, previously was a 1.5 diameter, was built ok but when firing the coil it gave of some nasty looking vapour, looked poisonous so I smelt the plumes and the smell so vile like a dead animal, I took a drag anyway and it taste like a dead animal too, iv replaced the cotton, it was still there, remade a 1.5 coil again and it's still there, iv experienced burnt taste and dry hits but this is so disgusting I dont want to play about with it anymore
