Too fragile. Two rotating drones I gave to my niece (9yo) and nephew (12yo) - one lasted 4 or 5 minutes before crashing and burning out (metaphorically - the rotors broke so it was done). ; The second lasted 45 seconds before crashing and shattering the rotors. They're beautiful to look at and interesting to look at, but they must be stronger because they'll be gone in a minute, two, or four.
