I'm having a wild ride with my new Silver Firefly.
I previously reported that my new silver unit was functioning exactly like my first dark grey unit. Eventually I started noticing that it was a
tad warmer than the grey one. I also noticed that the gap between the glass bowl and the metal plate seemed bigger on the silver unit, allowing more material to slip under the bowl, past the screen, and onto the metal plate. So I decided to try changing the screen to see if a different one would slide around less inside the bowl.
That's when the combustion started
I was using my normal technique and...flash of flame (visible even above the FF glow), acrid smoke, nasty burnt cherry in the bowl.
Well I snuffed it out and set about cleaning the Firefly to try to get rid of the smell. I chalked it up as a fluke until two sessions later - flames, smoke, cherry. I had even backed off on my button press time to prevent it from happening again!
Not to be deterred, I cleaned the unit up again and got ready for the next session.
I had been using 8 second button presses after the first draw, so I figured I would cut it down to 4 or 5 and see how it went.
One-one-thousand...two-one-thousand...three-one-thousand...four-one-th...COMBUSTION!
Again flame, smoke, cherry!
Frustrated, I took the top plate off, lifted the bowl assembly off of the ceramic components, and tried moving the coil around slightly (and
gently). I cleaned and reassembled the unit with a different screen. After tightening the top plate the gap between the glass bowl and the bottom metal plate seemed somewhat smaller than before, with the screen fitting a little more snugly. I've run several bowls through it since, and have not combusted. I am still using much shorter button presses than before though.
It really seems to me that the combustion started after I changed the screen. I was careful not to apply too much pressure to the other components when doing so, but it still seems to me that changing the screen somehow changed the way the unit worked. It seems to be almost a completely different vape than when I got it.
Something tells me that there are ways that the Firefly performance can change, depending on how things are put together, how the screen sits in the bowl, and how much of a gap there is above the metal plate. All speculation of course, but something changed in my Silver unit.
