Advantages: Awesome drone. Stable, strong, holds position even in wind, good flight time. Slows down during descent when gets close to the ground. Returns home. Auto lands when battery gets low (don't fly over water...). You have to do the compass calibration procedure right. Manual says do it slowly, but don't do it too slow. Do it outside (to get gps lock)! When the blinking stops and the leds are fully lit, it's ready to fly.
Limitations: No real cons here, but: - You take it out of the box, and then it doesn't fly. You have to read the included manual, charge it, learn the controls (label the controls), do calibrations, then it flies at all. - You can't shut down the motors quickly, that would be handy when grinding the wall. - Looks like a toy, but it's a serious drone.
