The black paint seems to scratch off pretty easily but it's not a deal breaker

I had to return my first copy as the ring made a ''sandy'' noise when turned, as if dust or sand had gotten in between the rings. My second copy had the same issue (but it disappeared after a few twists of the rings) so I believe it's the manufacturing process.
The filter seems solid. Nothing fancy about it, just glass with no coatings. I believe they used aluminum, but I'm not sure. The black paint seems to scratch off pretty easily but it's not a deal breaker.
The filter works exceptionally well, just take a look at the pictures I added. The filter creates reflection-less images and brings out the true color of the sky or any object for that matter.
Overall, a nice addition to anyone's bag, and a must have for bright sunny outdoor shooting.
