I've used one and it's not bad but doesn't line up perfectly. If you trim it first, real close to the black lines, you can line it up good enough. The top outside black lines close to 2X and 3X were a little challenging to line up and I found it easier to trim some of them off. I also removed the original paint under the overlay especially on the inserts. If your playfield has ball marks the new overlay stands out a little because it's so nice compared to the ball marked areas near by. Overall I was satisfied but my original playfield was pretty bad in that area.
