Question about Ryze Tech Tello

This is a toy. It is suitable for "everyone", you can't break much, but you shouldn't expect anything from it either. The part is intended for windless places or the living room - photos and videos cannot be compared with other multicopters, the camera is more of a "nice to have".
A rechargeable battery is included in the scope of delivery; it can be charged via USB using any 5V USB power supply unit or, in a pinch, directly on a PC.

For more serious things, the Spark (with RC) is certainly the better choice. For a bit of fun flying, however, the Tello is the perfect choice.
