If I were making large batches I would seriously consider scales. However I trust the old Mark 1 Eyeballs to read a syringe without error. I am just not too much of a trusting soul in tech. I have worked with it for most of my life.
Now I need to decide whether to boost my nic level up some... Maybe in my Desert Ship which I vape in the mornings and after eating....
12ml nic, 20ml VG, 1ml DIY steep and top up to the 100ml mark with PG ... a months supply mixed in 5 minutes
