@EnemyLemon -
Here's my experience with Vapman and how it relates to other vape devices. I vape dry herb only -- no oils, concentrates, waxes, etc., and have not combusted (other than rare tokes at a parties) since 2017. I enjoy the ritual and don't mind if a vape requires learning a certain technique.
I have almost a dozen Dynavaps from 2018 to 2021, including both SS and Ti tips, both old and new "captive" style caps, and many aftermarket stems including a Ti Simrell. My wife uses Dynavaps pretty much exclusively and loves them. She has no interest in learning a technique and prefers the dead simple "click" of the cap. I usually use a torch for optimum control, while my wife likes her induction heater for convenience. The Dynavaps have a *much* more restrictive draw than the Vapman -- I agree that's the DV's main negative. I've never been bothered by hot cap although my wife did swap ends once and burned her lip. The DV taste is excellent with the first hit, but gets progressively worse until you end up with burnt popcorn taste after about 3-5 full click to click draws. The Vapman has such a tiny bowl you don't need to suffer through many hits of bad flavor to fully extract like with a DV. I prefer using the VM for several smaller tastier hits throughout the evening rather than one or two big bowls from the DV or other vape. I rank the Vapman firmly ahead of Dynavap for taste. The Dynavap is more pocket friendly and bulletproof durable though, so it will probably remain my go-to for travel and camping.
I don't use my OCWW or SBL butane vapes as much anymore because I have been reducing my intake and focusing on microdosing. But both are excellent artisan products capable of producing huge clouds with a practiced technique. The Vapman's technique is definitely a little easier to master because you have much lower risk of combustion. You're also not directly inhaling downwind from the butane torch with the VM, although that's never been a concern of mine. (Bourbon and cheeseburgers will kill me first.)
Well that's a lot of words, so hopefully I answered your questions!
