Yes the hopper is very nich. It's intended to be ran though water.
The milaana is almost a desktop replacement. Problem is, IME, it's just real pain to teach newbs. They always combust. The Zion would solve this by giving them some "training" wheels to learn on.
While yes lowering the voltage supplied to the heating element isn't exactly the same as temperature control, it does perform that function... It lowers the entire curve. Will lower the heats ceiling (where the curve levels out and becomes very straight) and also decreases the rate at which the element heats up too that ceiling.... So yes decreasing a haters supplied power does reduce temp... But no it's not exactly temp control, nor regulation, nor does it come with temp display. And none of that is actually needed nor functionally important at all, or the cloud xhail evo, non digital volcano, enano, etc would all be considered junk instead of iconic... No?
Hopper obviously doesn't have that problem, but also obviously can't Zion. neither... It's grate for what it's intended though, now if my second one would just heat up as hot as the first one! Any way, the only point to the hopper drop was simply to point out it DOES Have temp regulation and will never combust on my guests as just can't quite get that hot.
The Milaana can also be putting out much hotter vape with the short stem IMO... So I would assume Zion could as well... Problem solved with longer stem, wooden stem, or bent stem, w.e. Grasshopper can be solved with a piece silicone whip tubing...I'm sure aftermarket mouthpieces will come out too.
So yeah... What ever. They are very different... Just have the same almost instant on convection feature. Wasn't really trying to go too deep into comparisons here. Sorry.
Really really want that Zion. Just waiting on it and TOD. Thinking TOD was scrapped...
