After watching a best of 2015 vaporizers where the five stoner "judges" went gaga over a small glass object they called a vapcap, I became intrigued . A little research, and I picked up an M, and some extras (pre M starter kit). I watched videos and tried to make it work. As I got way too many combustion episodes for my liking, I went back to my Solo, and picked up a pax2 . Fast forward 10 months, and my urge to try a ti tip to see if that makes a difference, and here I am again! Last week, in the get a pack of ccds with free shipping, I also ordered a lighter, a dark wood nonavong, XLS condenser with dark wood mouthpiece, and I am again off to the races with stoner Lego. Oh, and the combustion issue? A bit more practice, about 150 pages of forum reading plus the best of, and switching to the quad jet lighter DV sent me, and no more combustion!
