How much e-liquid will I use every day? Week? Month?
This all depends on what set up you are using. If you are sub ohming you can go through a lot more liquid then someone that is using a pen style vaporizer. With the pen style the average is a 30ml every 2 weeks with constant usage. Where someone that is using a sub ohm set up can go through a 30ml bottle in roughly 1 week. Again these can vary depending on how much someone is vaping.
