Well I have had the firefly 2 for about a week now. Pretty happy with my purchase. I spent the last year or so strickly doing edibles. But considering I am in a state where nothing is legal yet I had a hard time finding what I needed on a regular basis. So far this thing is great. Gets me high which is the only thing that matters, I could care less about the vapor production. I find taking some small draws while it heats up then ripping on it once the light is solid works best for me. Also slowly raising the temp as I take more hits. Pack it in the morning and I am set straight for the entire day. Also love that I can hit it and just set it down and come back when ever I want.
