I use a Nord 4 with the RPM2 mouthpiece. This is the first juice I’ve had issues with. The mix does not absorb into the coil. I tried multiple coils meant for different wattages thinking the coils were the problem before mixing some of a different brand in with the butterscotch. The other juice helped deliver the Glas and I could taste it. It tasted good, but I can’t recommend until the mix can absorb into the coils on its own. Perhaps a different delivery system would have better luck.
