I'm sure you'll enjoy the Yeti. I just got my Dura-C from Janty today and it is awesome. I got some banana cartridges and strawberry e-juice and topped off the cart and it's been like vaping a smoothie all afternoon! I didn't think I'd go for the fruity flavors, but I've got to say it is pretty good!
Thanks everyone! Just ordered my first ecig, a Yeti 510. I didn't realize the USB passthrough was also a battery, so I may well get that in the future, but for now I want to make sure I like vaping enough to continue. Same for extra batts; I'm usually near an outlet, but if I find that the two don't cut it, I'll get another, or build one of those portable battery packs I read about in the DIY section.
Can't wait to try it, and it's great to have the support of the community.
