DNA Chip - There's a premium sure. I have no problems paying for a better device. I have the stable to prove that. I'm holding an SXK Billet Box right now where I paid a 40% mark up just to get a DNA chip.
Button Placement - As you mention, 100% subjective. It's not my favourite placement either, but for me it's workable. Because it's subjective we should set it aside.
Battery - The only time it has blown through batteries for me was when vaping in excess of 65W. It doesn't matter what chip you use, if you're vaping in high wattage ranges you're going to burn through power.
The best I could find googling is a ~10-15% better run time on a DNA chip vs your general Chinese offering. I don't have my puff count to battery usage data, but let's say I get ~3.5 hours out of a rage when i'm vaping 80Wish. Seems reasonable for my constant chain vaping usage. That's 210 minutes. An improvement of 10-15% is 21 to 31.5 minutes.
On a 16 hour day, assuming i'm chain vaping all day long, that means i'd have to swap batteries 4 times on a rage. It also means i'd have to swap batteries 4 times on a DNA chip.
My point of view is not that the DNA chip isn't worth buying. It's the mass production Chinese grade quality that doesn't get solved by buying a Lost Vape product. If we're going to spend $250 CAD to buy a run of the mill mod with a DNA chip, i'd rather pay $250 CAD to buy a non mass produced chinese grade mod with a DNA chip. And even at that point, at $250 CAD we aren't exactly pinching pennies. I wouldn't care about spending $50 or even $100 more.
If it makes people happy and people want to buy it, go ahead. There's no reason not to if it gives the buyer their money's worth of satisfaction.
People should buy whatever makes them happy. If there's a demand for a chinese mass produced quality mod with a DNA chip, at a price point into the hundreds, then it will sell. If the buyer gets their money's worth of satisfaction, then I encourage them to buy what makes them happy.
Personally, when i'm looking at a mod that costs hundreds of dollars, i'm in territory that is well beyond smoking cessation. I don't mind paying $250 for a mod when it has $250 worth of performance, craftmanship, and build quality to go along with it.
Let's look at facts here. You can get a DNA250C board for a retail price of $90 CAD. That means Lost Vape is pushing a mass produced mod, costing the same in tooling, quality, production, and overhead as any other cheap chinese mod, for a $160 CAD premium. I sure as hell wouldn't pay $160 CAD for a Smok G-Priv. You can point to a Chinese website and say that the mods are selling wholesale for much less than $250 CAD, but I can guarantee you they aren't paying $90 CAD for each individual board.
