(32 PCS) Mini 4 Pro/Mini 3 Pro Propellers Compatible with DJI Mini 4 Pro/Mini 3 Pro Blades Props Wings Replacement Accessories (NOT for 2022 DJI Mini 3) | Drone Replacement Low-Noise Quick-Release Blades Props Accessories with screws & driver. Not for Mini 3 (2022)

I only bought this set from Amazon because DJI’s official spare parts were unavailable. Unfortunately, the screwdrivers included were completely useless, as you can see in the attached pictures—they arrived with broken tips. I purchased the 32-blade set, which came with 4 screwdrivers and a set of screws. When I attempted to use the new screws, I was shocked to find that they were not as slim as the original ones and did not fit flush. I had to remove them and reuse the old screws. Due to this process, some of the screws now have damaged heads, making it impossible for me to remove those blades again. As a result, I have lost my drone because of these cheap, faulty propellers.

They work and can get you up and in the air………(long pause for effect), however they are not DJI spec and the weight actually activates the prop guard detection. When this happens it will turn off the 360 obstacle avoidance feature, it also during certain times they affected the flight characteristics making my 4 pro fly like there was a Tinker Bell jumping off an on the rear. Didn’t happen every time as I ran through all 3 batteries testing them but, it happened at least once every flight you never could tell what it was gonna happen and it wouldn’t stop.

These propellers are exactly not what you need for your Mini 4 Pro. It caused multiple altitude error issues and did not allow the Drone to go into tracking mode because of this. I don't know if it was the weight or the angle of the blade but either way I believe it forced the motors to spin faster, thus causing the High Altitude error. The Drone would also not hover very steadily. Yes, I made sure that the correct blades were on the correct arms. When I brought it into the DJI store, we swapped out blades that were from DJI and the Drone worked properly. The Drone has been working properly since I swapped out these blades for actual DJI blades. Unfortunately, you cannot get DJI blades in the US unless you somehow get lucky. So, you might have to experiment with different blades but I would not recommend these at all.
