Good quality, fits well.
Good quality, good thick plastic. Much cheaper than the equivalent from ToolStation or Screwfix. Don't know what country this was manufactured in, however; I prefer to buy British-made, but didn't see a country of origin on this. I replaced the four retaining screws with stainless steel screws; the supplied screws are coated mild steel, and they sit in a recess that will collect rainwater, and will likely quickly corrode... stainless steel will not rust.
