Ha the One is not that bad, like the Fury Edge (or is it like the Fury2) but session style conduction with hybrid convection and small battery/bowl.
It is easy, all HI work the same, all log vapes work the same, you load the stem as your bowl, steel mesh basket screens, then inhale as you place it on the heater (or if you are using like I do, with WPA, you will keep the stem upside down and turn the HI upside down to put on top as you inhale and then remove to clear as I described I think before?) There is a learning curve because pure convection on demand is pretty manual, it is you inhaling that is bringing hot air through the herbs and creating the vapor, so getting that down can take a bit of getting used to, but once you do it'll be easy!
No, like I said look at the thread, there are ways to buy it in America now, and Planet of the Vapes are probably going to be stocking it soon... Definitely better than the One, especially for your needs, but a log is overall superior if you are going to be using at home anyway imo
Oh yeah it really is not complicated, you don't have to use water, there are a lot of options for dry pieces, even just using a water piece without water in it, having the volume to fill with vapor, but a longer path with bends and turns, potentially other things to help provide more cooling... I also like turning the log upside down to put it on top of my bowl and removing to clear my hits, I never use it direct draw with the stem like a straw on top of the log, though I did when I first got my underdog way back when and my original HI... Honestly using through water is what helped me learn how to hit pure convection on demand properly, helps you get your airflow right, the draw, like I said that's the part that is manual since that is what is creating the vapor, your inhale...
Technically the X-Max will work the same, a little simpler perhaps with the regulated small form factor to just rip it inhaling, but yeah it's really the same technique involved!
Sticky brick is also on demand pure convection, but yeah the torch, that's why I did not recommend that style of vape for you...
Yeah these are going to all taste better and be much more efficient than your One, and they should be smoother as well... Having a larger pathway is going to smooth out the vapor a lot though in addition to having it be pure convection...
Vapor is not magic, you're still inhaling hot air, and there could be herb particles, if you are not filtering through something...
