Ruining the symmetry" is the real fear. I do a quick tug test on every fitting while the air is off, because a visual check can miss a slightly loose hose. That saved my last piece from a lopsided disaster, @thomas.sandra.

Always thought those were just for driveways. Might have to get one now.

It's the same story with so many tools and gadgets these days. People blame the product when the real issue is skipping the basic steps. Feels like a weird refusal to read the manual.
