Er, I guess?? It's a convection device powered by butane (i.e. torch), so the physics are similar, I suppose.
They are both good at small doses, too; but if possible the Vapman is even more analogue than the Vapcap: there is no click, and I've never successfully one-shotted a Vapman. It's more of a flavour-intense, sippin' style conduction vape, while the Dyna is more of a one-hitter. That might be my lack of technique talking, tho. I've nailed my various Vapcap combos, and with an FMJ I can truly get one-heat-cycle extraction; whereas the Vapman is a "heat... was that enough... couple seconds more... still a bit wispy... ah, there we go"
They're a great vape with an impeccable pedigree and a loyal following for good reason; imho criminally under-rated.
No worries! It's a great vape, I suspect any detractors have not got the technique down pat (altho, as I prove, you don't need to have perfect technique to enjoy it!). It is often described as functional art, and I have to say I can't disagree. It's definitely a connoisseur's vape - not in a snobby way, but those who just want to get from A to B as fast as possible will likely have no truck with it; it's something to be savoured and enjoyed, for those who enjoy the Ritual(tm). If that's you, and you like butane vapes, it's a lock afaiac.
