Vaping, Electronic cigarettes

PS The more aromatic and sugary are and the quicker they fuck the coiler.

I thought so too, but it really depends on liquids... I have some very dark RY8 from pink spot and similarly dark stuff from the same brand (Jungle virginia) and the RY8 does leave lots of burnt residues on the coil, but somehow the Jungle virginia affects the coil far less while being sweeter...
