Mr Lamco I will be honest in saying that as far as flavor goes, I do prefer twisp liquid, but the liquid from cig-e is fine, "smokes" well and the cartridges seem to last longer than the Twisp cartidges [although the mouth tips are more a flexible rubber as compared to the hard plastic of the twisp cartridges] I will use liquids from both, as the price difference is a lot greater than the flavor difference, if that makes sense.
Both places have good service in my experience - Steve at cig-e has been really excellent in the service department - he even posted me goods before receiving payment to ensure that I had then before I go on holiday - not many people would do that and even though I know I am trustworthy, he doesnt' really know me.
I use the Twisp [Janty] stick, dura C and the Twisp [kissbox] classic.
