Not surprised to hear that, I am a bit suspicous about the quality
. I have formatt resin grads now and some of them have resolution issues, and all have reflection issues of course as they are uncoated.
I've heard a lot of good things about Lee resin grads, but they are resin and uncoated. I don't like to put that in front of my expensive glass lenses... oh well, I've got really paranoid about reflections. With my current grads any little mistake lead to ruining the image with reflections, and even if perfectly shaded bright objects in the frame may cause reflections.
(size is no issue as I'm using Schneider digitar lenses, my largest lens diameter is 67mm...)
