Very disappointing to here. I was about to try the Dura as my next e-cig because you need batteries some of the time (looks a little silly with the passthough when you are out and about)--glad I read these posts--Thanks for the feedback!
Still getting 4 to 5 hours on my battery's and I know others are as well.
Maybe some of you guys have defective battery's or they were not properly
conditioned when you received the kit.
It's important to let it have a full 12 hour charge right out of the box
Not just on this e-cig but anything that runs on a battery now days to get the full potential out of a battery and max life.
If you did this however and still not getting a full 4 to 5 hours on one battery something is wrong and you need to contact Jeff I'm sure he will replace the battery
Thanks
