I am using non-DJI props on the Phantom 4 series for about 2 years and if I had to fly back with the Phantom 3 Pro, would do the same.
I used Master Airscrew, Ultimax, wooden Xoar.
Lately for some months Aero-naut (or Aeronaut) carbon light, they are fine and a little bit less noisy.
Pay attention to Master Airscrew, the last type made with the built-in bolt has the defect (for me unacceptable) that is not firm, not stable in its plastic seat, has a small slack, it rotate a bit on his axis. Thus, from this point of view, it immediately behaves like DJI props, these often having the same defect, or immediately, or with the use, after some flights.
This can be easily solved by placing a couple of micro drops of acrylic adhesive that can infiltrate by capillarity between the bolt and the propeller, so to eliminate the slack of the last production, new series of Master Airscrew props.
Their production could have also another defects showing a not efficient quality control, the screw of the adapters can be bad made and not let to insert and rotate the props.
In that case need to ask them for a free replace if you don't have spare parts.
