The Tornado vapes great no major drop off in power/vaper untill just before the button starts blinking. The first charge on the first battery lasted me 11.25 hours. I'm some what of a heavy vapor from 9:00am till 8:15pm about 3.5ml's of juice. I think this unit is great as long as the battery hold up. Anyone out there know how long the battery will last (weeks months) and if the there is any major drop off in usage? I will be buying more of these batteries if they last.
