I don't think the point of the firefly is to have temp control through out the session because that's not how they intended it to be used... perhaps idk I haven't been reading up
? It's not like a flowermate or air from my point of view.
Now I've never even used the first one but it seems like the MFLB but with convection instead of conduction. It's a lot more manual than your average automatic. So with the new temp control just kinda reminds me of the PA, you set it to where you like it and then go from there, you really control temperature with your draw rate.
Though I could be mistaken.
