I’m sure DJI has made a quality product. What I don’t like is saying, “ real world tests.” They say if you do any of these things it will void your warranty. There are too many variables to their tests to prove that what is happening is a real situation. A little trickery maybe to make it look stronger than it is. (Maybe the walnuts already had cracks in them before the test?) That’s why,” don’t do this at home.” I just don’t like that type of advertising.
