Installed one on my Bm66 from new in 2017 and it still looks and plays great.Maiden got one installed in 2018 from new and thats the same. Both where from pu-parts.com in Germany and I wouldn't hesitate using them again.
I did play a Bm66 at a show which had one installed and it looked like it either been used as an ice rink or cleaned with a scourer.
It was scratched terribly. As long as you keep marked and chipped pinballs off the surface it'll look great for years.
