Now, my main issue with the novas is getting constant juice flow into the coils, so that the flavor/taste is consistent, EVEN when chain vaping. What happens a lot when you "chain vape", you loose flavor, and get a burnt/bad taste. ESPECIALLY with thick, VG juice like bobas. Simply tipping it doesn't help. So, the only solution I found is to cut little nitches in the rubber cap, where the wicks come out. Problem with doing this is that it is a BIG pain in the .... PLUS you have to be veryyyyy careful how small you cut the nitches, because if you cut them too big, then the nova will flood and gurgle. and once you cut your nitches, lining them up perfectly with the wicks while screwing the cap on is ANOTHER challenge. SO as you can see, the novas can also be a big pain... its a love hate relationship.
