A product warranty is a promise made by a manufacturer or seller to repair or replace a product if it has defects or issues within a specified period. This assurance helps consumers feel more confident in their purchase, knowing they have support if something goes wrong. Warranties can vary in length and coverage, depending on the type of product and the company. There are different types of warranties, including express warranties, which are clearly stated, and implied warranties, which are automatically provided by law. Understanding the terms of a warranty is important for consumers, as it outlines their rights and responsibilities regarding the product.
