We just got started vaping, a month in, and bought 1 new ce5 clearo (for use with ego 900mah passthrough) when all of our ce4s but 1 burned out. We ordered some Volcano Magnas to try out too, but we are finding that we like the clearos better (easier to fill, less mess), except that the ce5 seems to be burning through liquid like crazy. Almost 3 times faster than the ce4s. Is that normal? We did change our eliquid slightly. a larger bottle (18ml instead of 6) and lower mg (12 instead of 24) but its still a 50/50 blend of pgvg. Other than that, there are no other changes. Changed to 12mg because the 24 made us jittery, 12 seems to be good, but its going really fast. Please help.
