You are not ruffling any feathers....
I'm still catching up, and I'm sure others have chimed in.
I started with cigalikes, and quickly moved up to eGos, ProVari, and the like.
My quest, at the time, was decent battery life, good taste, good vapor, and an "automated" feed system.
I very quickly grew tired of changing/charging batteries several times a day.
Filling cartos that didn't hold near enough to satisfy me, or filling the tiny little eGo
tanks that usually leaked more often than not.
Even carto tanks, while a huge step up in my opinion, have their own shortcomings.
So.....
With the Zen, I get anywhere from 3 to 5 ml of
juice right there where I need it.
Not leaking out of a carto tank, not having to fill it every couple of hours. Plus, it's attached.
Nothing extra to lose or fall off or wonder if it's threaded correctly to fit my device.
I get battery life, depending on how "chain" I chain vape that lasts me at least most of my day.
I do, however, usually have multiple units going at once, but still, the battery life is gabs better.
I get good taste, because I'm not sucking through cotton or whatever that filler material is.
I get good vapor.
I get warmer or cooler depending on how many wraps I make. In other words, my atty is MY atty.
Not something pre-made, but made how I vape.
And it's cool looking.
And it's all-in-one.
And it's cool looking.
And it fits in my hand nicely.
And, it's made by a seriously nice guy, in the US, who hires in the US, who vapes and knows what he's doing.
My two cents.
