Ikenvape, I have a question on part of a response you made above " I can easily make a carto to last months, but wouldn't because of the inevitable destruction to the batting during regular use and/or unknown nature of the house mixed liquid. Harmful stuff."
From what I have read on this forum, most people will say replace the carto when the taste starts to go, or when the draw becomes tight. This made me start thinking, if I have been
vaping on a carto and it's been 3 weeks with no problems, shall I replace it with a new one any way? The cartos have been lasting a long time but reading your statement made me think maybe I should be replacing them more often.
Is there a time frame that you would recommend replacing cartos even though they still vape well?
Thanks
