I have a pen now and its great but I'm looking to vape my shatter a different way when at home. I always read people talking bout dab rigs but I have no idea what that is. I am confused on what a oil rig is and what I am even looking for. I do know that I want something that will get me more ripped than my pen, can be used with all concentrates, works well with shatter and wax, needs to be small and compact, and I would prefer to not have a giant torch blowing in my living room. I used a rig a buddies house and I was amazed and scared for my life that he was torching up in his living room, I would prefer not to have a giant torch for the sake of my animals. what should I get? what are the basic pieces needed? Besides a pen what are my options for consuming concentrates? Thanks!
