Are you using prebuilt coils or the RBA deck? If it's the prebuilt coils that came with the beast, they could be shotty quality. I've always had better luck getting a fresh pack of coils for some reason. If you're using the RBA, make sure you have enough cotton in the juice wells, but don't pack it too tight. It needs to be able to breath if it's going to take in juice. Is the tank leaking at all? What is your VG/PG for the juice you're using. And, if it is the stock coils, did you let it sit long enough?
Not trying to undermine you in any way, just wanna cover all the bases to get the best understanding of what's going on with your device buddy
Vape on!
