Third batch just got released. I don't think there's been enough time for them to be delivered yet. Many people who got fired up over the gogo bought the second batch and most are happy with the unit. There does seem to be more button issues with that batch than with others. As I stated, I had some problems with the button at first with the Nhaler, first kit, but charging and changing the way I vaped the device to avoid condensation at the connections seemed to solve the problems. Now all four of my units work perfectly. I'd be the first one screaming on the site if i had problems.
