During the first use of drone My son was a victim of Fly away phenomenon apparently well known manufacturer (the Parrot forum is filled with similar complaints.)
The drone hand in the air regardless of height limits defined and flies up losing the connection of the smartphone / ipod without reacting aus descent and landing commands.
Of course it is impossible to find after the drone.
Some customers we got a replacement Parrot drone. I made the same request. I will complete my review with the result of my request.
Apparently it is essential to update the firmware drone before first use. This is not mentioned in the Quick Start Guide or on the packaging.
