One 30ml will last you one month, you should not be refilling more then once a day really, if you do a complete fill. I have a few flavors and keep 2-3 carts filled at one time, so really the 30ml will last me like 3 months due to that since I smoke 3 flavors I only refill it once every 3 days. But if you get down to it, that's one months worth![]()

Condoms come in different sizes, too, or at least they used to.
I think the 'factory' dosage for prefills is just short of 1 ml (I think).
And yes, the number of drops can be different, I am guessing 30 to 40 drops make a ml, but the size of drops I can easily change from one dripper to another, and sometimes within even the same dripper.
There is an old Internet proverb, "YMMV" There are people on this very forum who use 30ml every few days. What works for you doesn't necessarily apply to anyone else.

So it is best to start with aleast 20 drops,taste then add more if needed for the taste and the vape.
That would be a good start. On average most people feel 20 drops is 1 ml, but that's only an average. As Addy points out there are dozens of variables, I might also include altitude, atmospheric pressure, humidity and how steady you are with the container.
