I ordered a few of these for a renovation project, they are a huge improvement over the ugly contractor-grade ones that we had, very stylish and refined looking. Having a few of them to compare to one another, they are not 100% consistent in quality and symmetry. You're not likely to have them next to one another, so probably not a huge deal.
One caveat, my dog freaked out about something and got her paw stuck in it once, the openings are a bit large. The vent just came out and she stomped around for a second (damaging the hardwood) before i ran to her and removed it... but I reluctantly might be swapping these out AGAIN for a less ornate version with smaller openings. I hate the idea that that could happen to her with no one here and she could possibly get injured. Or permanently freaked out about the floor attacking her! :) Dogs.
