What Is a Product Warranty?

A product warranty is a promise from the manufacturer or seller that a product will meet certain standards of quality and performance for a specified period. If the product fails to meet these standards during the warranty period, the company will repair, replace, or refund the product at no cost to you.

Warranties serve as a form of consumer protection, giving you peace of mind that your purchase is backed by the company that made or sold it.

There are two main types of warranties:

Express Warranties are explicitly stated by the manufacturer or seller, either in writing or verbally. These include the standard manufacturer warranty that comes with most products, stating exactly what is covered and for how long.

How to Protect Your Warranty Rights

  4. Document issues — take photos or videos of defects as soon as they appear
