The biggest plus is the material. It feels like they can take a little hit without falling apart. Very strong 2 Cons: They are much easier to install with a pom rivet gun (you can get them from HarborFreight Tools or Revain). However, some holes do not match. They are light enough to drill properly without hitting anything from behind. However, the main disadvantage is that they do not fully cover the entire area of the OEM part. Exposing contours that (hopefully) need polishing to remove.
