Official DJI ND filters vs 3rd party?

[Singularity]

Has anyone used both? I'm wondering if I should get the DJI ND filters, or just some cheaper ones off ebay?
What do you think?>

If you've had a positive experience with 3rd party ones, please let us know which brand they were. Thanks!

I have dealt with optics in my day job and considered buying raw filter glass and 3D printing my own mounts. Turns out this would cost me as much as the third party vendors. But then again, my sources provide high quality filters.

I was hoping that someone would find some ridiculously cheap filters online.

I have the PGY tech ones. They are good but cannot compare them.
Majority are using the Taco RC as they are the lightest and have no issues.
Polar Pro first gen should be avoided as they have obstruction issues. The second gen cinematic series have resolved this issue.

Any of the filters listed here would be okay to use. If you decide to buy a brand that is not on my list, make sure the filters can be installed while the Mavic is powered down.
