The quadricopter made really fun! After little tasting I had the hang of it and a lot of fun with it. When I wanted to show my friends the evening after a few beers in the courtyard, but I have unfortunately exaggerated. In approximately 50m height (it was almost only to realize a black dot in the sky) was a gust of wind and it is still not emerged.
So: Do not drink and fly! Otherwise, just buy it! Great device at a reasonable price!
