Has anybdy tried these foldable low noise props? https://www.ebay.com/itm/4-Pair- ... TPFi2Ao_zOg9cE-bdLQ
Or any other low noise props sold on eBay? If so what are your results?

Hi there, thank you for sharing. I tried to check the link that you posted it seems not a foldable propeller and since we don't have a foldable propeller as well for the Mavic Air.

I wouldn’t risk my drone on 3rd party props!

The props in the link are either standard or (more likely) rip-offs, i.e. not foldable and not low noise.

I would never take the risk.
