I've had my Firewood since Saturday and have used it for probably five sessions now. The first three sessions were definitely a learning experience. I do feel that there's a bit of a learning curve with this vape (like nearly any vape), and it has a lot to do with getting a feel for when to hold the button and when to let off. My first session, I had trouble getting any visible clouds. The second, I certainly got clouds, but I felt like the taste turned to burnt popcorn quickly and the session was over far too soon. Third session was more of the same. In my defense, I came down with a nasty cold and/or flu the same day and my concentration definitely wasn't what it should have been.
I just tried out my fourth and fifth sessions today with much better results. I'm getting a better feel for judging when to push and when to release. My sessions are lasting longer, I'm getting at least 6 - 8 quality hits, and my ABV is uniformly brown.
I like this vape. This is something I really wish I'd had in college! It's a great value at this price point, it's beautiful, and it feels pretty stealthy to me. Yes, it's bigger than an MFLB, but I can still slip it into the shallow-ass pockets of my girls' jeans with no problem. And I can't detect any residual smell after a session, and much less during a session than a Pax or even a Solo. I've not had many sessions yet obviously, but the cleaning/maintenance is less of a concern for me now that I've observed how thoroughly I'm able to dump ABV out of the unit. I used a pipe cleaner to reach in and gently brush a piece of herb off the screen at one point, but the unit itself is staying surprisingly clean. The mouthpiece will obviously require more maintenance over time as the spring coil tends to collect resin, but even that doesn't seem like it'll be a big deal.
I'm definitely feeling the two sessions I just had!
Overall, I'm happy with this vape. I sprang for the Walnut and it's just gorgeous.
