I've got a firefly 2 I don't use anymore because it needs maintenance, a firewood 5 and a firewood 7. I love them all. I hardly do any consumption besides dry herb vape anymore.
There's a mouthpiece you can hook up the FW7 to a bong/perc but I haven't gotten it. When I upgrade to the FW9 (or whatever they're at when I have the money) I'm going to get that.
