Just wanted to chime in again here with my thoughts. I haven't read this thread much since I posted last, but I have been falling in love with the Firefly 2 more and more with each use! I'll be honest and say I had a tiny bit of buyers remorse when my first sessions weren't as desirable as I had hoped, but that has turned around completely.!
I was almost ready to write this off as a vape I'd only use for oils, but with with the right technique, it is amazing with herb! A 4 piece grinder, a somewhat coarse grind, and packing the bowl fully as well as pushing down on the herb a little, but not forcing it too much has been the key to success for me. I also like either medium-high (ramping up to high later in the session) or just high as my heat setting. I have also let it heat up for a bit longer than the indicator says to. A long medium to hard draw gives me clouds very comparable in density to the Grasshopper or Evo in my experience. The vapor is amazingly cool for not using any water and the taste is very good to me (though I don't get top shelf). I still find that stirring in a session is necessary for me to get full extraction, but even doing this quickly with my fingers (taking about 5 seconds or less) is adequate enough to get the job done. I can get my ABV as dark is I desire with it on the high heat setting.
As others pointed out, I find it to be a very great complementary (make jokes about insects complimenting each other here) portable vape to the Grasshopper as well as the to the Evo. It won't replace either unit for me, but it will also continue to have a spot in my daily lineup. I really can't imagine needing another vape at the moment, but I've said that before
. I tried to keep this brief, but that never works out too well for me.
TLDR = FF2 + GH + EVO = Perfect for me! (As is each vape individually). A little twisted, so I hope this all makes sense!
