I have a theory on that. I think early on for alot of us using high VG or 100% vg, we went llooking for a better system than carto tanks. I personally started
vaping Boba's 100VG after the first couple of weeks vaping and it just is so thick it did not play well in alot of tank systems and such for me. I went on the hunt for something better, found another bottom feeder and realized this was the solution for me, then went looking for a durable bottom feeder and have been in Reoville since then. I now do 95% DIY and vape 80vg-100%vg Boba's is the only vendor juice I still occasionly buy.
