Front landing leg extensions fell off in the first flight. They are held on by friction only and I guess the vibration was all it took to drop them off although I had no excessive vibration warning. I pushed them onto the existing Mavic legs as far as they would go and they seemed secure but when the drone returned after a 20 minute flight, they were gone. The back legs snap on and were still there. The gimbal guard , stick protector and lens hood are fine but the leg extensions were my reason for the purchase. I gave an extra star for the other parts that seem ok.
