Read a lot of reviews before buying this drone. Yes, the features are great! Ease of control, good camera, stabilization. There is only one BUT! It looks like I'm one of the "lucky ones" who encountered some kind of navigation error. Launched in the field, far from any places that interfere, calibrated before that. Everything is as it should be! It took off, flew for about one minute, after which the drone went off and it flew off in an unknown direction, it was not possible to catch up with it. That's it, the drone is gone. Haven't been able to find it yet.
