I don't necessarily think people are comparing them directly, more so in the sense that if you limit a ball vape to a roughly 0.1g bowl, extraction efficiency between the two is comparable. The physical constraints of the herb chamber in the Anvil are definitely going to create an unfair comparison, especially when you can load upwards of 0.5g with some devices. Having said that, I also don't see the Anvil as a replacement per se, but definitely something that complements my desktops nicely.
To be clear, I agree that instructions are required and at the very least an online instruction manual of sorts is definitely something that should be provided for the benefit of new customers going forward.
Having said that, I think the comparison to Dynavap here is a little unfair. Dynavap has been in operation for 7+ years now and while they had some videos early on, they were pretty similar to what
@Whiff has been providing to my best recollection. If you take at the Dynavap page now, most of their instructional videos come post 2018. I'm fairly certain during the launch in 2015 the instruction situation was pretty similar.
