After a few weeks of use I thought I would chime in again. I've been researching grinds and heating techniques, all in the name of science of course, and have reached some conclusions.
The FF is incredibly versatile, you can get any kind of draw you desire just by altering your draw method or grind. Clouds or small tasty hits without changing heat temps are easily obtainable.
From the first hit to the last the taste is unmatched by my other vapes. Every different strain I sample has it's own unique flavors.
I tried the whole unground bud method and was rewarded with yummy new flavors, take a couple hits, flip it, take a few more then break it up, simply wonderful.
Between cleanings I use the supplied brush then a blast of air to clean for the next bowl, if you trim about half the length of the narrow long bristle side it becomes stiffer and more useful.
I had to re-seat the small o-ring under the window a few times with the supplied toothpick. after tightening the screws it hasn't moved.
Iso and q-tips work well for cleaning, I try to keep the iso from the o-ring.
The FF has become my vape of choice, and I'm thankful for it and this great resource for discussing it.
