Then the same thing happened again but it smashed into a wall and broke a prop

That broke the guard and prop

It broke the prop

Third, while noted but not really explained, if you get into trouble, you can land your drone in relation to where it is by double pressing the one button takeoff or simply kill the props for an emergency stop by holding that same key

Right out of the box, all I had to do was charge the battery, install the prop guards and landing struts, sync the controller to it and fly

In several months of frequent flying, we've only broken 2 props and we've crashed many times.6

One point worth noting, the drone comes with prop guards which I recommend fitting to protect the props and also the house walls
