I bought one of these recently and have been flying it in the house, and a little in the back yard.

It's amazing. Check out the video below.

Caution: The control range is only about 100 feet, maybe 150, and if it goes out of range it doesn't auto-return. Don't ask how I know. OTOH, not a lot of financial risk.
