Agreed. "Quality" is a shortcut word to mean an aspect of a product/service that many/most think desirable.

There are examples of seemingly contradictory high/low cost, high/low durability, high/low reliability, high/low status symbol, etc. and seemingly every combination.

Cars are a great example:

* Reliable cars can also be cheap.

* High status symbol cars can be incredibly expensive but also unreliable.

* Expensive cars can be dangerous.

* etc.
