Used it for two years now. While we almost exclusively use the polarizer filter out of this set, I can attest to the quality of each of the lenses. Given that we shoot over water 90% of the time, in very sunny environments in Fort Lauderdale, Miami, and other South Florida locations, we love the results we get from the polarized filter, great for filming above boats, where even the white deck at midday has contrast, detail, and clarity that's simply unattainable with the standard UV lens on the Phantom 4 Pro - whereas before the whites simply were blown out. The video we've captured at sunrise looking down into the waves rolling into the beach is absolutely stunning. Even on a moderately cloudy day in Point Loma outside San Diego, the polarized lens added so much detail to the cliffs, as well as to the surfers in the breaks where the white surf maintained excellent detail. I've gotten some great footage as well employing the ND filters flying inches above footprints in the sand on the beach and got a great blurry cinematic look near the bottom of the frame as the drone sped along.
This is an absolutely ESSENTIAL piece of gear. So happy with it.
