I'm really enjoying the Anvil. Sticking with induction heating for now, easy to dial it in for a perfect dark brown roast in one hit. I've combusted once, so I know the limits. A second or two can make a difference in ABV color.
I have some minor complaints. I don't like the air adjustment device. I can get it to work, and I understand the principle. I don't like the fact that the air adjustment device isn't screwed tightly into the stem when assembled properly. I am able to assemble it correctly, and I am able to open and close the air intake by twisting the stem and visualizing the line in the window. I get that it works based on the threads in the stem turning. But it seems like I often need to take the stem off, reposition the air adjustment device, and reinsert it into the sleeve to get it back snug. Otherwise something seems to loosen and the stem turns a little. Also, when I turn the stem to adjust the airflow device it is a little rough and can squeak. I think adjusting the airflow is overly complicated and relies on pressure exerted by the user, rather than just an easy twisting action.
When properly assembled my unit still has a slight "wobble" if you grab the bowl and the stem and wiggle it. Nothing that seems to affect functionality, but just seems like it could be more solid in that area.
There are some machining imperfections on mine. There is a small but obvious burr on my thermal battery, on the side adjacent to the air intake valve. And I think the ends of the bowls could look a little more polished. Both the full bowl and half bowl that I received looked the same - not bad, but not polished.
It's still a great vape and is turning out to be more versatile than I thought. Great vapor, thorough extraction, easy to operate (as long as you're OK handling hot things).
