What is causing the smell is the foam in the Firefly box. The foam smells very strong and it is transferring to the FF2 device. The odor is not caused by the device itself but from the white foam packing material.
If that were the case, I would expect the outside to smell (which it does not), the smell originates from the inside of the lid, and pretty clearly points to the gasket I think.
That being said, I've used mine for 4 bowls, and the smell is completely gone for me. No trace.
I LOVE it! It's exactly what I was hoping for, and will probably be my primary portable vape this summer.
My 2 pieces of feedback:
1 - I wish I could change the heat setting from the unit itself. Like a double tap of both buttons or something.
2 - I wish the glow showed up more for the user, while toking. It looks great for everyone else, but I wish I could experience the glow more from the top of the device while I'm pulling. I think the FF1 was a little bit better about that. It's a complete nitpick, but it would make my experience a bit better.
3 - Custom heat settings - Right now, I wish I had a setting in between Med and Med High. It would be cool to be able to choose the actual temp for each profile. (like the crafty)
**EDIT**
I should note some of the positives as well, to be fair
1 – the size / weight is fantastic. Much improved from the FF1.
2 – The lid design is much better. It seems like there is less draw resistance from the lid (as chucks would always get stuck in the grooves), and it is so much easier to clean! No more cleaning the grooves and channel, just wipe it down.
3 – heat settings! Pretty standard for most other vapes nowadays, but it’s a nice addition to the FF line
4 – Swappable batteries, that are the same as the FF1. I love units with swappable batteries. As I already had 2 for my FF1, it’s awesome for trips that I won’t have power for a while, and peace of mind that I could bring 4 batteries with me.
5 - Same FF experience - It's still the same root experience as the FF1 - great fit / finish, excellent vapor quality, swappable batteries, easy to maintain, all wrapped in a very nice user experience.
Bravo!
