Thought I'd start a DynaVape thread since my M arrived this afternoon. The M is a small cylinder looks like about 3.5 inches long with a diameter of 3/8 inch. The M itself appears well made and solid though I think the magnetic cap that slides on the end is a bit thin with the little digger stem a bit flimsy so we'll see how that stands up over time. Took a couple practice draws to find the air hole and put about .05 gram for 3 small bowls. First I'm impressed by how cool the vapor is for such a short air pathway, it's one of the things that concerned me as my only experience with torch toking has been shatter on a nail heated with torch which I haven't enjoyed because of the heat and coughing, of course I'm not going full loads yet so we'll see what happens then. First couple bowls didn't get much beyond a nice terp taste though third bowl got a nice 2nd hit. For these tester bowls used some Desil , grown organic outdoor and didn't quite finish but had to take down because of PMS (Powdery Mildew Syndrone) and bud rot starting so probably only 14% thc I've been making canna coconut oil, cannabutter and gummies mainly with it, next bowls time to break out the organic Nuken which finihed early October and probably about 20%thc, not up to my usual standards but it'll have to do for now. So far I like the DynaVape M, easy to use,seems well made, the AVB (after vaped bud) is nice and even brown with no sign of combustion. Back later with an update after some supper when I'll pack a few full bowls .10 of the Nuken and let 'er rip before the hockey game starts.
