SMOK Novo 2 Refillable Pods

I am a SMOK Novo fan. I have owned two Novo 2 devices and two Novo Pro devices. I love that the pods are interchangeable. I do, however, prefer the top fill pods, in place of the side fill.

I always have plenty of these on hand. The pod juice starts to thicken, or it leaks into the battery.This system needs to be cleaned out all the time.
