A more thorough explanation:

Quality-of-products legislation, also known as lemon law, is a law that protects consumers who purchase a product of inferior quality. This law requires the manufacturer or dealer to either replace the product or refund the full purchase price.

The most common example of lemon law is for automobiles. If a consumer purchases a car that has repeated defects or malfunctions, the lemon law requires the manufacturer or dealer to either replace the car or refund the full purchase price.

Another example of quality-of-products legislation is for appliances. If a consumer purchases a refrigerator that repeatedly fails to keep food cold, the lemon law requires the manufacturer or dealer to either replace the refrigerator or refund the full purchase price.

These examples illustrate how quality-of-products legislation protects consumers from purchasing products that do not meet their expectations or perform as advertised.
