Bad, low quality product. Don’t waste your time/money. Specially:
One of the props without the white marker meant to be mounted on a motor without a corresponding white marker will not mount because the hub on that prop is meant for a motor with a white marker. Certainly fits perfectly fine when I tried that (mounting unmarked prop onto a marked motor). Again, the prop does not have a white marker and has “N” stamped on the hub (N is also stamped on props with the white marker). The other prop without a white marker has “R” stamped on the hub and fits an unmarked motor just fine, as it should. So much for actually testing them to see if the reported vibration issue has been addressed or to see if they are indeed quieter.
Edges on 3 props look much rougher when compared to the 4th prop.
One of the props is certainly a different shade of orange than the other 3 props.
Disappointed to say the least. Left a voicemail and sent email regarding return instructions.
