The 15-degree angle made all the difference for our porch—we finally see the full walkway instead of just the mailbox. It clicks on firmly and feels like a genuine factory part, not some flimsy third-party knockoff. Took me two minutes to swap out and the view is exactly what I wanted.
The tilt is just enough to stop the sun glare on our porch, and the mount itself feels solid once it clicks into place. Installation took maybe two minutes with the screwdriver already out. Only wish it came with a second one for the back door, but that's on me for not ordering two.
