I've spoken to Amazon at length.
From their responses, they have never held or sold any Rova drones.

Feb 14 anns by IOT stated will be exclusive to Amazon for 90 days from March.
Also they stated would be from early March.

Amazon's website had sales starting date as of March 5th.
They are now taking orders since March 5th, but there are no Rova drones in stock and therefore no delivery date.

One can only assume the delivery from AEE to Amazon was either
a) never made or
b) still on its way or
c) there are no drones.

IOT have one product to sell, in fact Amazon are selling it for them, it really is not that difficult, is it?
