The plastic seems sturdy and has a nice quality feel to it. The picture looks a bit darker than it actually is. I rated 4/5 because (in my case) the cap is about 2mm shorter than the original Fender cap that it replaced, so it does not fully cover the knurled part of the tremolo arm. It's only visible from up close and is not a deal breaker to me, but I think it's worth mentioning for those people who want absolute perfection in their builds.
