Is Roam-E going to be another Zano?, page-123

Ah, yes, but we concentrated on professionalism rather than survival. Professionalism was the key to survival, which is why we still retain our first customers after over fifteen years.

Part of professionalism is not over-promising and under-delivering. That would have been terminal. And being sure of our technical abilities was important too. I think it was you that queried knowledge of physics. Perhaps you could explain how the flying selfie, with today's battery technology, could possibly fly for four hours as IOT claimed a year ago? Even with this year's level of energy densities that is still way outside the bounds of possibility - according to the physics. Which really calls into question the technical knowledge of the IOT team back then.
