The app feels like it was written by a first year high school computer science student. It is extremely difficult to get the drone to fly more than 5m up. it just holds there and then goes wildly up and down, crashing into the ground. (while holding up the entire time, with a fully charged battery on everything, and GPS connected, and right next to the drone). I'm not going to lie, this was one of my first drones and it really put me off from flying anymore in the future. It is unusable in its current state. Waste of money
