I intend to read this whole thread but so I've only read to page 60. I had to stop and post because my MFLB arrived yesterday. I started to write this right after I got it, but then I tried it out...
Executive summary: this is a superb device. I already own an Arizer Extreme v3 (not the Q) and I love it. For me, the MFLB is the perfect complement.
I live in the Greater Toronto Area and I was disappointed and somewhat puzzled that I couldn't find any local vendors carrying this gem. I ordered online from vaporizers.ca and was pleased with the service. Last week, when I went to place my order I was informed that they were on vacation and orders would resume shipping July 12. I wanted a vendor this side of the border so that was fine by me. Wednesday (July 14) I got email notification that it had shipped, and Thursday (thank you Canada Post) it arrived. Potential customers note: it required a signature, just in case that matters to you. The packaging is wonderfully discreet, plain box with a return address for Nature's Way.
The Launch Box itself is exquisite, a brilliant piece of engineering and craftsmanship. I like the stealth and the price of course, but the thing that appeals to me most is that there's no waiting: insert battery, hit, done. Over in 20-30 seconds. That's even faster than lighting up. As far as I know, nothing else compares to this.
Just to re-emphasize a couple of things: grind exceedingly fine, and draw really slowly. I'd read this advice before and thought I was prepared but I still nearly overdid my first hit. I'm a counter, that is, I can't help myself from counting seconds while I draw and while I hold it in. So, I'm used to drawing for "One thousand two thousand three thousand..." I intended to go to about 20 on a really slow draw but I had to stop at 10 because it was starting to make me cough. I got a much thicker cloud than I expected, especially given what I've been reading here about people who can't seem to get thick vapour. When I looked at the load, there were a few little chunks stuck to the screen that were almost but not quite black. I am pretty sure these would have combusted if I had continued on to 20.
I crumbled the load up until it was much finer and I drew even more slowly for my second hit. Success! A nice medium-thick vapour and nothing sticking to the screen. I stopped at 10 because I feared overdoing it, but I got a great hit anyway. I don't find the effects to be any different than from my Extreme, but perhaps that's because I'm used to vaping at 160-190 with the Extreme. I suspect that those who like thick vapour tend to get it by vaping at higher temperatures, where you get a different mix of active components and hence a somewhat different buzz.
Also, I notice some posters criticize the MFLB because it leaves some goodies in the AVB. I consider that a benefit myself. I can put it into the Extreme and take it to a higher temperature (although taste is affected) or I can use it for one of the many AVB techniques for squeezing out every last bit of goodness. Incidentally, even AVB that I've taken up to 240 in the Extreme still yields goodness with QISO or tincture or cooking. You can even get a decent buzz by (yuck!) combusting it. Bottom line, MFLB AVB is great stuff.
Anyway, I must go now. I have to double-grind my stash.
PS I'm such a doofus, I nearly forgot. Thank you magicflight for this wonderful piece of ingenuity, and for the unsurpassed level of customer support I keep reading about in this thread. Thanks Ariel for directing me to a Canadian source. May you soon find some vendors in the GTA.
