What is a warranty?
A warranty is a type of guarantee that a manufacturer or seller makes about the quality of their product. It usually lasts for a certain period of time and covers certain types of problems. For example, a one-year warranty might cover defects in materials or workmanship, but not damage caused by normal wear and tear.
Warranties can be either express or implied. An express warranty is an explicit promise made by the seller about the quality of the product. An implied warranty is an unwritten guarantee that the product will meet certain standards of quality. In most jurisdictions, implied warranties are automatically included in all sales contracts unless they are specifically excluded.
Some warranties are included free of charge, while others must be purchased separately.
