Yeah, my cartotanks were on the sideline for a few days, too. However, perhaps because my experience with cartotanks is longer and more familiar, they are a more dependable setup than my AGA's.
When the rebuildables are working right, they are superior to a cartotank. So far I have found their performance to be inconsistant, though. This could be from my own inexperience with them, as I have used them for less than a month. They'll be working great and then out of nowhere the vape will change. I'll check and the ohm has changed by a full 1.0 ohm. Without going into detail here, I'm still troubleshooting what can cause this.
Having said all of the above, I still prefer using my rebuildables on my Provari over my Silver Bullet because I still like adjusting the voltage to my particular flavor being vaped.
