Just got mine as well, and should have some more detailed feedback shortly.
One thing I noticed (that I didn’t catch initially) was that there is protective film on BOTH sides of the lens. At first I only noticed/removed the film on the more obvious side, as the other side didn’t appear to have any film in place. Also, the attached instructions states to install with the textured side out, and that the clear film side is textured. So, at first I thought there was only one “clear film” side. At least on my sample, the film on the non-obvious side was on there very good and perfectly round. It actually took a bit of effort to get the film off that side once I finally realized it was there.
So, to all that received these as samples, be sure to take the film off both sides!
