@Hobbit2233 When you sold out in Aug '16, the drone on offer was the Roam-e, which is yet to be released to the market. The most recent ann that had updated info about the
Roam-e was released 4 May '17,

One of the Roam-E features as announced at the time, was the Follow Me function.

Subsequently the ROVA selfie drone has been released to the market, particularly targeting the US market as ann 16 Jan '17

The fly time for the ROVA, in my experience with flying the drone, is up to 8 minutes depending on what functions you use. Taking photos only doesn't use much additional battery power, but videos and the 360 degree function depletes the battery quicker, as you'd expect.
ROVA comes with 2 batteries. The recharge time is about 30 minutes plugged into 240AC adaptor. Longer if recharged by USB port. When additional accessories are available online, I will purchase 1 more charging unit and 2 more batteries, as I fly most days.
cheers
