I just started this and do to the burning toxic odors smells I think i am done. I have a few friends doing this and showed me all the way around this and not one worked.
Dont give up. Everyone gets that burnt hit when they are low on juice. If you are doing cart mods and getting even a little piece of that filler up in your atty you might always get extreme toxic hit. What nobody tells anyone is that the 510 attys are extreme machines and they burn filler. I don't know why I don't get as much support when I say to try a drip tip. They are the newest and best thing for e cigs. And I don't know why people wont start to tell the truth about the carts. I used to use carts and I got extremely nasty hits and after I got new attys and a drip tip I can tell when I need to drip long before I take that burnt hit draw. Plus when your dripping when you do get that burnt hit its not a combination of filler and what ever else causes the burnt hit. I'm sorry but if its a sin to speak my opinion that is mostly a fact then I give up.
