Has anyone had experience with this filter?
If so, please tell me what you think of it.
Thank you.

didn't try it yet... but Polar Pro seems to  be making good filters

My order with Polar Pro is on back order. I have confirmed from multiple sources that all of the filters are of great quality. You should not be dissapointed. Depending on the lens you are using, you may or may not have to balance the camera. If you are using the DJI stock lens, no balancing required.

I have a set for my Pro  Excellent quality
