I go through about 10-15ml a week with my aspire ETS BDC on my KBOX. I have been wanting to switch to sub ohm vaping. I have found that 12mg/ml is the best ratio for me in the ETS but I think I will move to 6mg/ml for sub ohming. I have a horizon Arctic tank coming in the mail I am wondering how much more juice I need to buy. I have heard it chugs juice using the 0.5ohm coil but is the 150 ml (10x15ml) sampler I just ordered overkill?
