I was trying to figure out which I'm sensitive to, VG or PG so I ordered 100% of each. The VG doesn't work in cart well as I found out the hard way - and when it finally worked, it produced a burnt taste. Then the PG I ordered...well, the taste is just ucky. So would a 30/70 and a 70/30 both work in a carto? I don't want to order anymore that won't work in it. I use a eGo battery with CE4V2 cart. One eGo says eGo and nothing else. The other says eGo T. Thanks!!
