KINGWON Low-Noise Propellers Blades for DJI Phantom 4 Pro+ V2.0,DJI Phantom 4 Pro,Drone Quick Release Props Accessories,4 Pieces

Quieter than the standard blades, same lift

I can't say they are useless as they do lift the Phantom into the air.However having compared them to the standard props using a sound meter app on my phone there wasn't any real difference, maybe 1-2db at most.I then filmed them both and stitched the film together and tested the sound meter through my laptop speakers.Again about the same noisy level.My biggest concern was the fact that they are much loser fitting than the DJI ones, almost 5mm of circular movement.I think over time with the force of the motors on start up and the play in the fitting this will lead to the locking struts at the top of the motors snapping.If they'd have been a tighter fit I'd have kept them for the price of £11.99 as they are much sexier looking than the standard ones.But I wouldn't want to trust them at altitude with my P4 Pro.

Worked as described, not as vibration free as original DJI product

DJI quote a 4-5 decibel drop with their own propellers, after some testing with a decibel meter swapping normal DJI props for these and on a Phantom 4 standard I got between 5-6 decibel drop and you could tell a big difference 100 feet up, a lot quieter so highly recommended.

Great props using with a first gen phantom 4 pro does make it quieter lot harder to hear when 200ft up great for filming around animalsas well made as the dji ones

Very good product AAA

Difficult to secure to drone motors with a poor finish

very poor fit, you can hear the props rattle when you reduce the power, I'm not trusting £1,500 worth of drone to these props..
