I've never had any issues with the iClear30S. Pretty solid for a clearo in my book. Once the heads get old and I go through their replacements I may consider trying to find a carto-
tank to fit recessed into it though. I get tired of keeping up on cleaning cycles. Plus, I want to be able to vape any flavor I want on a whim without worrying about it corroding my plastic. Since I'm using a carto-
tank on my 134, it'll be easier to keep parts stocked too instead of worrying about two sets of parts for two different PVs.
