I finally got my drone working again…
I finally got my drone working again thanks to the good effort of Maria Luisa, who answered my mail prompt every time within 12 hours. To bad she had to depend on the person who had to write a three line letter to get my drone working again. This took for ever (several weeks). Maria Luisa had to defend this person's lack of enthusiasm and apologize for it. But after all she managed to get me the letter and my drone is fixed. If it was for her I gave this review 5 stars, the whole experience 2 stars.
