Just get you some extra heating coils is really all you need. Unless you want a different style drip tip.
Those coils will last a good week - 2 weeks or longer depending how much you use them.
But, since you cant really replace the wicks you get a lot of flavor bleeding if you try to change flavors.
I mean, you can just change flavors and use the same coil. But it might taste a bit nasty at first. And some flavors may linger. A strong Cinnamon or Peppermint flavor for example, will tint your next flavor for a very long time and hard to overcome them.
Although Sometimes its pleasant. A strong Peppermint then changing to say .. Milk Chocolate. The Peppermint will linger and you'll taste it with your chocolate. If you like Peppermint patties though, you are in good shape
What I done with mine was have a coil for each flavor I had, and a couple extras for replacements.
I'd keep that coil in a little plastic bag when not in use and label the bag with the flavor it was used with. That way I could use that flavor only with that particular coil.
When I'd change flavors, I rinse it out the tank, swap heating coils and flavors.
Im the exact same way and tire of most flavors pretty quick. Although I can vape some longer than others.
But I have a 3-4 flavor rotation per day.
Changing is a good thing. It'll help prevent you from getting that "vapors Tongues" as they call it where your juices loose all flavor.
Have you got your Zeus juices yet? Curious how they are doing for ya.
