Sorry, I just saw this message (new to messaging here). I just didn't like them. they got very warm and seemed harsh and I didn't like the tips that came with them. . I'm now using the clearocartos from Nhaler and they are working well after a week of use. My problem with them mayhave been the ohm rating as the normal g6 cartos are 2.8-3.2 and the CE2's were around 1.8. That alone would make them burn hotter. possibly a higher ohm rating would have worked better. Plus they were a pain in the .... to fill. Again, sorry it took so long for me to find this.
