Hey all, I'm about 2 and 1/2 days in with my new Echo, abolutley loving it and do not ever intend to return to analogs! I'm wondering about the cartomizers though. My first purchase included 5 cartomizers and 4 different flavors so that has been working out well so far with switching between the four filled with different juices and having one empty on stand by, but after getting started and enjoying it so much I felt the urge to try some more flavors. I currently have a variety of other juices on the way from rawrvapes. Do I need more cartomizers if i want to try other juices or can I refill one that I have with a different flavor without effecting the taste?
