HeiyRC 9455S Low-Noise Propeller for DJI Phantom 4 Pro V2.0,4 Pieces Noise Reduction Props for Phantom 4 /Advanced/Pro Drone

Good product lower noise

Works great

...the "quiet" you get is more of a lower, deep hum sound. It's still as loud, but because it's a lower pitched noise produced by these props....it seems less annoying! Balanced perfectly: took off and lifted 20 feet and hovered in place....dead set...not drift at all. I cannot comment yet on others claims that battery life is longer. I cannot tell if the lift is better with these or not. I also love the way they look. For less than $11...these have been a steel.

Theses props are cool looking and work great ! Very close to the originals in quality. Can't beat the price !!

wings super light weight and flexible hopefully in strong winds and P4P model won’t angle of attack will remain constant with multiple flights and time

Working just fine.

I bought them because they were cheap. They look good but they are very brittle feeling. Have no flex at all. That worries me. I think they should have a bit of flexibility considering all the different angles and changes they have to go through. They haven't failed me, but after thinking about this. Why would i trust my 2000$ drone with 11$ blades? Makes no sense so I'll be buying a good set and keep these for emergency use. They do work. Seem a little louder than normal though.

These look just like OEM version except for lack of DJI logo
