Are name-brand rainfall heads worth the premium over Amazon brands?

Specialist subreddits are split. r/HomeImprovement threads we read repeatedly warn against Amazon-only plumbing fixtures over counterfeit and longevity concerns, especially for in-wall valve systems. For a simple screw-on rain head, the risk is lower — but for full ceiling-mount systems with rough-in valves, several plumbers in those threads strongly recommend Kohler, Moen, or Hansgrohe instead.
