As some say, no need to use better material than the one customer wants

We humans are dumb when buying stuff, as we choose cheaper solutions and sometimes end up paying more when replacing the cheap alternatives.

But I do that myself too. I can think of something good enough so I do not need to spend 30% more for a better material.

However I am delighted some companies think carefully through even what plastics they are using for the best results instead of choosing cheapest one.
