One of the attached propellers was lose but fortunaterly there were some extras in the delivery. The quality of the videos considering the price was OK (1920x1080 20fps) but the shield of the propellers were visibel in the videos. I think the Optical Flow is quite stable. The manuvering with the remote control offered some concern as the control system was the opposite of the movement of the drone -the left and right and up and down positions were the other way around. You can only stand 30 - 40 meters from the drone before you lose contact and if you are unlucky the drone disappears. Unfortunately I couldn´t recommend this drone.
