These are the gateway drug to the world of multi-rotor craft and if you look around Hubsan's site you'll see where all this is going. They fly well in large spaces.
Or in a home or office space.
After a few crashes the propellors need to be replaced, spares are available. The other thing that goes pretty quickly are motors which either become stiff or die all together. Good news is that it is possible to replace them with some fine soldering.
Each battery only lasts about 6 minutes so you'll want to get extras and there are multi-chargers available. All charge from a USB 5V port.
