Ok, tried to take a few notes to see about battery life etc, number of pulls, amount .13g, grind etc...
What I find that works consistently for me is:
If I set it at say medium or even med low, with a coarse grind, I get a decent cloud, nothing crazy, but I can easily see it. 1-2 pulls at around 20-25 secs with lsd making sure it doesn't whistle and I feel the meds easily. Taste is amazing as if I'm eating it. Once I notice the abv color changing to a little bit brownish, I bump up the heat to med high. I usually get 6 more hits that are still decent size wise but taste has really diminished. I usually do this over around 6-7 days and my battery doesn't die on me and usually shows full still which I know isn't possible.
Coarse grind, with gr8tr, .10-.13g, fluffy still, packed a little over the over and lightly tamp down. I found that a hand tear for me produced very uneven abv and didn't produce nearly as consistently for me. I do stir fairly frequently though, probably once a day. I look at the abv and see what it looks like and if I see brown in the middle I stir, simple.
I use this around the house, discreetly, and typically in garage and doesn't produce much smell. I will not say it's no smell at all though. the unit has a smell of the contents when you first load it, but after that it's a little bit of a burnt popcorn you smell but not horrible. Most wouldn't notice it in your pocket, but if you put it near your face your going to smell it. Vapor is not very smelly at all, within a minute I can't tell or smell anything. My wife, who is a non toker, has walked in right after and didn't notice anything and has never smelled it on me. You can taste it in your mouth though, smells like fresh yummy meds at first but after it Browns some you will taste the popcorn, lol. I find that one load lasts me about 6-7days at my current rate, 2pulls a day and I usually have some left in it but want to change up so I dump it and clean it(which takes about 1min). This ff2 is really really good for me and my wants. Only thing I would like if I could dream it up would be for it to be a little bit more stealthy. Other than that, it's absolutely perfect for ME...
I typically get decent meds, Girl Scout cookies, sour diesel, or some kind of lemon something that's tasty. Worst case is some no name stuff but sometimes taste better than all of them anyway and does a good job every time...
