Hi welcome to ECF. I'm glad your issue "fixed itself" in whatever manner. I know almost nothing about those types of setups, I kind of chose to avoid them because I wanted more durable vape gear, and also, it's probably (even if refilling) one of the more expensive ways to vape, the vape can often fail, and etc.
If you are enjoying yours setup and finding success, by all means continue with it. However, most vapers have backup gear, and there are setups that would probably provide you with just as satisfying a vape, with less headaches along the way, and far more flexibility in terms of adjustability of wattage, airflow and other things that can really be dialed in to suit YOUR individual preference. I might do some research on the board and maybe start looking for different types of setups. If you are currently finding your setup satisfying in terms of draw and amount of vapor, I'd explore MTL setups. One that I'll often recommend is the Aspire zelos 50 watt kit. It will have a Nautilus 2 tank with it, and while it's an internal battery mod, it's going to be more robust than your current setup. The N2 is a good "beginner" MTL tank, it was my quitting tank (fair disclosure I've moved on from the tank to other, equally as good MTL vapes, but some of them are rebuildable and/or otherwise different. I still think the N2 is a good tank for starting vaping, and my husband is currently using my Zelos setup to quit (hopefully) himself.
I realize this isn't so much answering your question, but it's always good to know what your options are, and it's good to have more than one setup in case yours breaks. That can be unpliant if not prepared and etc.
Best of luck and welcome.
