Got my Black set of these props and was not totally crazy 'bout it. First, they don't have white color that will match my white spark. For $ 17.00 a set + shipping it's not worth it for a plastic non foldable props. Made a test flight and noticed it's still noisy but with lower sound pitch as the original DJI props has a high pitch noise.
Don't take my word for it, go ahead do your own testing.
I have been using MASTER AIRSCREW props on my builds and I totally love them, they are HIGH QUALITY PRODUCT and this is the first time that I am not impress on a particular props made by them.
