There’s a lot of stuff that works remarkably well even though it’s cheap. I just came from a supermarket. It’s filled with items from around the world, of which most are very inexpensive. The consistent quality of these products is astounding—a bag of potato chips or a box of crackers tastes exactly the same, anywhere in the country where I buy it, year-round. A can of Coca-Cola tastes exactly the same even though they’re bottled in different facilities with different owners.

These things did cost a lot to develop, but for the consumer it’s quite inexpensive. As GP said, we just take these things for granted and don’t notice them.
