I'm going to second ddjsvapor's suggestion, here. Even if it were the BEST e-cig ever made (some people think the Juul is the third coming or whatever) I wouldn't support BT efforts to insert themselves into the vape market. I'd check out some of the equipment forums and see if you can find something that works for you that you can use, repeatedly, SO MUCH cheaper, and as an (now, and I'm in a really bad mood today, I STILL have not smoked) ex-smoker, I don't want to hand BT one.more.penny.of.what.I.have.spent. As far as I'm concerned, BT can make itself useful making nicotine for vapers (that WILL be the way it goes, in the end, as far as I'm concerned, the FDA KNOWS that and that is why... They're getting interested in the vape market, eventually as people get educated, that's where the $$ is going to flow.... I mean, after getting OFF cigs, I am really disinterested in some "pretend" burning cigarette that is SLIGHTLY less harmful and NOT worth the price.
One of my docs told me that years ago, (we're talking '99 and he told me this was decades back) that as health effects were showing up, vaping was totally on big tobacco's radar and they were worried about all the data in the 70s coming out, and ALL considered switching to non-burning devices of various sorts, and decided against it. Instead, they made their tobacco more and more addictive, and smokers were smoking *more* due to all the additives, the drop off rate, etc. Now, they are reaping what they sow, making money off vape equipment that sucks (either deliberately, or because they want to be "different" than the vape market) and either way, anything produced by a tobacco company is going to be expensive, over-hyped, and likely fail, causing either a return to cigarettes, which is the ultimate goal, or getting people hooked on overpriced cartriges, so they continue to make money.
Rant over (for now)

But yeah, if it's not working out (I have not yet memorized all the cartridge style vape pens yet) try something new, and FAR cheaper after the initial purchase.
I'd start with a small tank, like the Nautilus 2 with a 1.8 coil (it comes with a sub-ohm coil, most smokers find it easiest to start with something similar to a mouth to lung draw, like a cigarette, but if you want to produce tons of vapor, you could try sub-ohming. As far as rechargable batteries versus something you plug in to charge, you are likely going to want something smaller for now.... There are lots of options, or you could jump to a one battery regulated mod. I'm not so familiar with the different tanks I'm sure someone will chime in though. Then, depending on where you live, find a vape shop that will let you try flavors, try a few, buy a small amount of a few flavors, and see how you do. You can go from there...
