If your expecting temp. control, you are probably in a niche market. Most people don't know what it is, don't understand or care, don't wrap their own coils, don't want another coil to keep track of, and are vaping as an alternate to smoking (not as hobbyists or sub ohmig 0% nicotine). The majority are not on line in forums. Both isticks and subox do step down and there are few others that do. I think Kanger's done their homework on what really matters.
Who couldn't guessed the kbox woud sell at all with limited wattages? I think Kanger knew that most people adjust according to taste and don't pay attention to the numbers. A lot of people are waiting for the tank alone to be release just because of the color. Asethetics do matter, as well as comfort and function. Both SMOK and Sigelei fell down by issuing another box.
It took me months of staking to score a 50w istick after I missed the coop. All I could find was black or silver. Blue and red sold out in hours. I'm getting a bit peaked at always having to spend another $10-$15 on top of retail to get something in a color I want, if a wrap is made for it. It wasn't available instantly unless I wanted to spend an extra $15 over what I knew it should be (+ $15 to wrap it). Vapor Beast's sale of < $20 wasn't a closeout since they've reordered multiple times, anymore than MFS's sale of nautilus at < $15 when they first came out ( that's the only reason I tried the nautilus). The sale pushed a lot of people into a new experience who otherwise would have no idea what they were missing.
Please don't misunderstand, right now we have the ability to customize vape according to what works best for the individual and I'm all for that, whatever that is yet I see manufactueres ignoring intermediate vapers. The subox fixes that.
I guess we shall see.
On the first video, one of the comments asked about white flaking off in the tank and the guy said that it didn't continue doing that. All tanks need washing before use. I haven't seen the second one yet. If it doesn't fit your style, fine but I wouldn't say jumping in on this preorder is dumb either. It's one of the few preorders that could make sense IMO. I wish I could too.
