Not a single bad 0.9Ω cCell has ever been found yet, and none of them in service has needed to be replaced yet despite some of them having been in service for almost 3 months that have seen up to well over a 100 tanks of use in that time. Some of that maybe because I dedicate each cCell to just one liquid... some because I don't push them as hard maybe with at least 5 mods being used all the time in every rotation so the cCell tanks do not get hot.
@Spydro I think this is the reason yours are performing perfectly... tanks with my not so favourite juices do fine... the ones I push hard are the ones that fail and I'm convinced it's because the cCell takes some punishment. That would also make sense why when I first get a tank it's fine for a few days and only later does the airlock issue raise it's head. My main tanks I vape intensely... I have just changed the cCell in my ORC and tightened everything down and so far so good...
The juice dump I understand perfectly... Melo III 4ml with a loose juice refill will dump overnight.
Despite the issues... cCell's still deliver the best possible vape!
