When you turn these things on, everyone gets up to play, including my 70 year old parents. Everyone is impressed. I absolutely recommend them.After buying the one-pack, I decided to buy the two-pack so I could have multiple in the air at once, and then give away the extras when we were done playing with them.These things are very lightweight and have the propellers inside the cage, so they won't hurt anyone if they crash (which they occasionally do).Comes with a charger and extra propellers fur each drone.Takes 50 minutes to charge, and runs for maybe 5 minutes (I did not time the flight).The instruction book rhymes!Downsides: The propellers may come off, but they are easy enough to put back on. Instructions say to make sure to disconnect the charger after 50 minutes to avoid damaging the battery. They may fly behind the furniture once in a while!
