Did or do you use it for a daily driver?
What types of concentrates did you use in it?
Did you clean the bowl out fairly well after every use?
I've only tried concentrates a few time recently. Mostly it was for the herb. But fairly resinous herb. When I started making my own rosin I thought I'd give it a go again using their concentrate pad and use small amounts. It didn't help. And really why should it, the pad is made of metal, it will get hot and then the melted resin will get into the holes. Heating it will not accomplish anything.
You need to take it apart to understand that it has a seal on each side of the bottom oven plate and also that the oven is 'spring loaded' as it were, there's a rubber o ring on that is used as a compression spring. So.... eventually this little bit of give allow crumbs and debris to accumulate between the glass and the bottom of the oven. There's no two ways about it it needs proper cleaning occasionally.
Yep, firefly can’t have it both ways. FF2 can be easily disassembled and the parts aren’t glued together so servicing can be done by an untrained steady hand.
Cleaning out those holes can be annoying since there aren’t any brushes with small enough bristles to punch through any accumulation that’s been softened with IPA.
About a half a millimetre under the holes is the ceramic oven, so it's not like anything can really be pushed through the holes. What you can use is a sewing needle, called a 'sharp', their points are more tapered and slender and you'll just about be able to get the point in, but really you need to do it from both sides.
But if you take it apart then you'll see that the circuit board seems to take a lot of wear. And the oven is black and the heating element looks worn.
Look let me be clear, I'm not pissing on the FireFly 2 without reason, I think they tackled a very difficult problem and they did pretty well but it has its flaws, none of that really annoys me at all. What pisses me off is that they refuse to allow me to service it. See that little flat heatproof rubber washer below. That's all I want from them. Eventually it's going to tear or just not seal as well and they answer is... to paraphrase "why don't you go fuck yourself"
I've had numerous correspondence with their nameless rude smart aleck "support" staff who happily talk bullshit to people who are not sure. They did it to me. I mean I did what they told me at first, they told me to do a burn off over and over until the battery wears out. That probably did a fair bit of damage to my FF2. Let me be clear these are factory instructions.
The electronics are already flakey without their pointless burn offs.
Also there's one other thing, we don't really need those fucking heating algorithms that some imbecile has decided is the way everyone must use it. OK have their algorithms, but they also need an "expert" mode, where the side buttons turn the element on when touched and off when let go, then I would be able to make it work for week as I like it to work.
Even from new the electronics were flakey.
See the crumbs that gather in the corner of the bowl, they build up in that space created by the seals.
When you press down on the bowl a little while cleaning it or wiping it out, the the O ring on the back in this image is used as a spring to push everything up. You can see this is a problem that will only get worse, it's the type of normal cleaning you'd do on anything you own. But here you are not allowed to. Firefly work on the principle that you'll be too frightened to brick your $400 vape and then they'll laugh at you and say 'we told you'. They truly are scum.
You may think your screen looks OK, when you try to look you can sort of see the little holes glowing when it's alight. But upon further inspection you find holes that are partially blocked, this is not easy to see on something that is only 100 microns in diameter.
You think your FF is clean, this is what you can't see....
