Anyone have experience with these filters?

These are on sale at Amazon and they seem too cheap to be any good. I would appreciate anyones input. Thanks.

Neewer Camera Lens Graduated Color Filter Kit for DJI Phantom 4 Pro

I had Neewer ND filters for my P3A and bought another set for my P4P. They are good, do what they should.
Having said that, I haven't got graduated colour filters - can't see any case when I would use them over photoshop. Graduated ND - maybe.

I do not own this package but I do own a set of ND filters by Neewer. For me they work just fine.
