A:AnswerYes. I have a DJI Mini 2 and have used it with these DJI Mini propeller guards. They are snapped into place on the extended propeller arms of Mini 2.
A:AnswerI dont think so. If the drone hit hard enough to crack the arm it probably would have happened even with the guards on. But your props might still be ok. The guards are more about protecting the things y(ou bounce in to and limiting damage to the propellers than anything else.
