DO NOT BUY. Bought these as a replacement kit for my DJI Magic Mini and installed them after the original props ran out. The hardware appeared to be slightly different in size from the original. This should have been my first clue that the installation wasn't complete. The first test drone took off and crashed in an alley, one of the props flew off at the first lift after installation. The propeller was still installed on the drone, although the propeller came off during flight. The drone is beyond repair and I had to order a new one to replace it at my own expense. Should have read more reviews before buying, expensive mistake. Save time and money, only buy DJI spare parts.
