A 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 some protection against potential problems. Warranties can vary in length and coverage, with some lasting only a few months while others may extend for several years. Common types include limited warranties, which cover specific parts or issues, and full warranties, which offer broader protection. Understanding the terms of a warranty is essential for consumers to know their rights and responsibilities.
