nice, i would likely be chrging while im sleeping so i could wake up to a fresh batt. and being able to use it for a whole day would be ideal. im puffing alot right now, i think its just while i adjust to the change. but sofar its satisfying the craving which im loving sofar. i didnt expect to be getting such enjoyable hits off this thing. i still need to find a good menthol flavor. the one im using now is the strongest menthol flavor, and its good, but its not what im used too. maybe i need a bit more time to get used to it, or maybe its going to be something i need to change. it has a kind of creamy, burnt after taste, if that makes sence.
