I have one. It is pretty fun to fly around, however, any kind of breeze outside makes flying a bit more difficult. I'd say the range is about a block when I fly around the neighborhood. There's a lot of wifi in the neighborhood so it does affect range too. It takes a little getting used too. Also, it has video capability so you can see things from its point of view.
The standard battery it comes with gives me about 12 mins flying time, but I bought a couple higher-capacity ones and a fast charger from a hobby shop which doubled it as well as lets me charge off my car-battery when I decide to go to the park.
