Nice review. I got mine about 3 weeks ago and loving it. Unfortunately i had to get it straight from China though, as i can't find anywhere in the UK that sells them yet.
I can confirm that you can charge 18650 batteries while they are in the mod, as i've done it at work when i was without an external battery charger. I did find though, that i had to gently wiggle the cable before the batteries showed up on the screen to tell me it was charging. 1 thing that is irritating me though, is that i can't find where to reset the puff counter :/. If anyone knows how to do it, i'd appreciate the help, thanks and happy Vaping.
