These propeller cages are better than any other propeller guards for the DJI Mavic. These will significantly reduce risk when flying near people or in tight spaces. With these cages the Mavic can still fly after bumping into an object. They do reduce flight time, but you can still get upwards of 12 minutes of flight time.
These must be used with Mavic - 7728 Quick Release Folding Propellers. These propellers are sightly smaller. The standard propellers are too long. This set comes with 6 of the Mavic - 7728 propellers.
Thanks for looking!
