After lots of research I decided on the FF2+ mainly due to the flavor it delivers. I concur & highly recommend this device but be prepared to stir it frequently. Cleaning is simple. Battery seems adequate so far. The app requires that you enable location sharing to connect via bluetooth or its useless. BS excuse IMO. You can set your temperatures manually. This fact cost a star!

After some minimal research I took the leap. So far, so good. Some initial nonsense with the charging adapter aside, the item is impressive. Light, intuitive, efficient and compact. Customer service was adequate and helpful. Satisfied.

Just got my FireFly 2+ and I love it. What I love best:
AMAZING heat up time (3 seconds or less)
AMAZING charging time (80+ in less than 10 minutes)
so easy to use
(unlike my old DaVinci, which made you wait till it cooled down before you could reload), you can just do bowl after bowl
AMAZING vaporizing: just keep it on and keep inhaling, you can draw for 15 seconds or longer and it just keeps up with you
plenty of room in the bowl

Haven't tried extracts yet, but looking forward to that.

I can't compare this to the FF2, because I never owned one. What I can say is that I'm happy with this Firefly. I've had no trouble with draw resistance. I also use a Milaana and a Splinter, so I'm used to modulating my intake. The resistance on the Firefly seems comparable to those vapes. The flavor and coolness of the vapor is as good as my Splinter, maybe even a bit better. I've had no battery trouble whatsoever and I enjoy using it. I would recommend the FF2+ wholeheartedly.
