Very surprised at their choice of a quadcopter which has four very obvious single points of failure. A hexacopter, or better still an octo with split flight controllers and power sources has some chance of recovering from a powertrain failure - an essential criteria for a multi-rotor designed to fly in or over populated areas, or indeed anywhere where the cost of the loss of the vehicle or payload is prohibitive. (None of which of course solves the problem of how you safely land and secure the delivery at the target site, but it's table stakes.) This is a hobby-drone cleverly positioned to senior execs looking for the new hotness without understanding the fundamental requirements for a practical solution.
