Honestly I don't care if anyone believes this or that. It is up to the individual person to decide if it is up to their standards. If you are the type of person to believe a certain group's opinion, then you are likely similar to those folks enough to base your own conclusion. This is why reviews work. Everyone has their favortie reviewer for what ever reason they've chosen, so if that reviewer feels as though its this or that, or this event occurred, then go with your own thoughts.
I say that to lead to this; the Smok Zmax is not, in my opinion, ready for release to the public. My Zmax has functioned nicely for a week and a half. Since then, it has been acting straight crazy-beans. When firing it will sometimes scroll through menus and change settings, sometimes it doesn't fire at all, sometimes the LED display dims and brightens all on its own accord. I use Panny CGR 18650 batteries, and the stock cap.
Pros: nice button, nice display, best size I could ask for, weight feels appropriate.
Cons: cap threads are kindergarten level design, cap spring isn't the type that can compress greatly, as the coils are same size throughout (this causes serious strain on the positive connection/board), electronics do not appear to be reliable.
Draw your own conclusions from my opinions, but I personally wouldn't mention the Zmax and ProVari as being anywhere near equals. The ProVari isn't my favorite PV either, so not really a fanboy. I think it is overpriced for what it is, so that makes me feel the Zmax is a bigger ripoff at suggested retail. At street rates you may get some value if purchased from a vendor who will back up the warranty.
