I hate to say this after Mitch's post (sorry Mitch!) and because I fear the almighty jinx but....my firefly is in a amazing shape. I still love it and it's still awesome. Not one dent in the paint yet. I haven't cleaned it two weeks and no problems!
Well, it's near my second week for the FF. I'm learning the learning curve. Steadily I'm getting better hits.
I changed the lighting in the room so I could see the vape. I found vape was coming out of the mouthpiece. So I made sure I was holding the mouthpiece properly.
I also put my fingers partly over the air vents when I take a draw. This restricts the air intake to the heating chamber. I find this gives a better hit.
I've got the red one and keep it in its original box. So it's good as a storage box too.
One thing that bothers me about the FF is I'd be mortified if there was a scratch on it. Small dents I can live with, but not a scratch. I don't know if that's a bad thing about the device.
