The XKJ KY905 HD 4k responds perfectly to its advertising. You can carry it in your pocket! The app is very intuitive and clear in its controls. Its camera is really good. By having two batteries you will be able to do more flights and stunts. You will have to be very careful with obstacles, as it is easy to damage the blades accidentally. I recommend it for photos and small videos, as well as for training future pilots. If you are going to leave it to a minor, always with adult supervision and in authorized open spaces.
