Let me elaborate. I am looking at the HI and the Underdog or really any vape but from what I read these are my best bets for my requirements for it to survive in my house. efficiency, ease of use, no glass, dry herb are my biggest concerns. Any suggestions would be greatly appreciated. Also is there a voltage regulator that is suggested? Thank you in advance for your responses! I am ready to get away from my volcano for awhile and my MFLB with glyphs are becoming my DD just because I am sick of messing with bags. I am a blank slate with no bias so all opinions are valued. Thank you!
