If you have trimmed the unit and has become accustomed to the tiny remote control you can keep the plane maximum 5 minutes in the air. The charging time is approximately 30 minutes. Walls and furniture are a problem, as the propellers are not protected against Aufprällen. At best, they just jump from the engine and then reinserting it and continue to use. But they no longer break quickly and with 3 propeller alone (or less) is flying the quadricopter. For each of the 4 propellers there is a spare propeller. But it's a good idea to be equal to one or more propellers, additionally required. - By the way, airmen and remote link when switching. So I could use two flyers with their respective remote control simultaneously.
Because of its small size, the plane is ideal for indoors. Outside you can also use it as long as it is not too windy. It is robust and holds a few drops from. But if he lies on his back, you have to turn it over by hand. So get out there better not control it somewhere where you him - when he crashes - can achieve only poor. For precision flights on the table the small remote control is not so good. And silently the drone is not. From the sound of her like a drill at the dentist only not quite so loud. - Stalking is not possible.
Conclusion: Quadrocopter remote control and fit into a shirt pocket. With practice, one can thus passable flying, eg start / landing from / on the palm. Without protection, the propellers are but the first victim. When the price is - I think - the top performance. But Beware! Once one has fun with it, you want more quickly. (Flying longer, replacement battery, better control, propeller protection, camera, etc.)
