I have been vaping for about 9 months and still looking for the perfect set up. I have tried the cartomizers that came with my initial kit and they sucked. I have tried v4l wow and cool carts. The cool carts were ok. Then I tried the ce2 metal cartos. They are a pain to fill and alot of times have a funky taste. I then tried the vortex and I really liked them other than some leaking issues and the top coming off. I would reorder those but they are out of stock. I have also tried the clear fluxomizers (clear ce2's). They work great but omg they leak like crazy. I filled 2 for the next days use and when I opened the case they were completely empty from leaking. I have read good reviews about the boge and also the new dual cartos. If anyone has used these type of cartos or used some of the ones I have listed can you please recomend a good carto. I want something easy to fill that works and don't leak. Thank you for any advice or input you can give me.
