wow, that is pretty, how the hell have I not seen that before???
I don't know River, you seem to be paying attention ;-) One has to like the box mod ergonomics, which I do. I agree that the TorneGo is a really good choice though. Perhaps the Mustang of vaping ;-) because of the styling. I took both on vacation and found myself hitting the Tornado mostly - lots of questions at the smoking areas at Disney.... I was holding seminars. lol.
But the Bartleby holds that peak voltage longer and lasts a bit longer too with my experience - 650mAh on the Tornado, 900mAh on the 14500 in the Bart which truly lasts a good 8 hours for me if that's the only ecig I'm using. 6 on the Tornado.
The other thing about the Bartleby is like the JStick, the charging cable acts like a PT where you can have it hooked up in the car and when you disconnect you're vaping at peak voltage - if you don't know what that is, you'll just have to experience it. It's a 3.7volt batt just like the regular 510's and the megas but it has much more power - meaning more vapor - for hours - see Scottbee's battery thread on what the actual voltage of the oem 510 batt is - like 3.1 and the difference in the Bart's 14500 is quite noticeable and real close vapor-wise to a 5V without putting your attys in jeopardy or burning out flavor.
Bart also has an on/off switch, something you don't get with many mods, to where you can turn it off, put it into your pocket and not worry about burning yourself ;-) And.... the price is right. It's worth it to read through that thread for the feedback.
