I Like 507-C quite a bit, but I have found it to have a less agreeable room note than, say, Luxury Navy Flake. Additionally, when I ordered 8 ounces of it a while back, it came in really messy condition-- I couldn't get separate flakes out of the bag, more like a broken flake. I've seen many youtube videos, etc. to tell me my experience was an anomaly, but if you're somebody who likes flakes to be very uniform and orderly, you may not get that with 507-C.
