I bought 2 sets of 8 Chinese props on Amazon for 2x9€. They arrived 20 days after the order.
I inspected them and my thoughts are :
- They are made of the same material, but not the same mold (mold closure line ‘plan de joint’ in French are not the same).
- print quality of the white circle for CCW props is poorly painted.
- overall dimensions look the same, but the inner diameter for the screw is so tight that it does not fit loose on it like the original ones. I had to reprocess all of them (1 hour work with a thin round file on a drilling machine, destroyed 2), to get the same gap (manufacturing clearance) compared to that of the original ones.
- After processing, it seems to fly Ok.
- The included tool is Ok
- There is another brand that sales for approx the same price on Amazon and the comments are the same, they complain about poor screen fitting...
... next time, I’ll order the original ones ! Avoid these...
