Overall great toy for kids and a lot of fun. One of the downsides is sometimes the sensor doesn't react well so it doesn't come back down on a full charge which is bad for us because we have a 2 story ceiling room so if it gets out of control and goes up there until it dies it will Definitely break if it falls. The remote won't react to it if it's past a certain height. But if it is within the short range it will work and turn on and off like it's supposed to.We used it outside and it flew away terribly made this is worth zero stars I only put one because I had toMy granddaughter had a ball with it. She flew it all over the house. Works great.She loved it! Nothing more to say!Very disappointed. Does not work
