If the Lily Drone got 35 million pre-orders at roughly $800 surely you could possibly think that the ROAM-e could get 5% of these sales reasonably easily.
There may be plenty of people who have ordered the Lily who will also order the ROAM-e for shits and giggles. You can take selfies of your Lily with your ROAM-e.
You just need a good video that goes viral and me thinks that they are taking their time producing a great video ! Maybe a big group-E shot on Bondi Beach!
