I'm not getting much flavour out of my Tornado-t and I've noticed that the remaining liquid gets much darker as it is used up, could the flavouring be staying in the tank for some reason?
Edit: the e-liquid is the premixed coffee from TW and worked fine in the cheaper cart fuelled e-cig that I had before.
