I vape 25-30ml a day, 1mg nic. I mix all myself so the cost isn't even noticeable. Dual TFV4's on IPV5 and Sig Spark. RC-1 Clapton rba (on both TF4), with a simple 3.5mm dia, 7 loop 24 gauge. It still pumps it out and goes through it fast.
My stock up supply (all new in box): 2 Sig Sparks. IPV5. 1 TFV4, 4 Subtank mini, 1 acylic subtank mini.
