About the site Lifetime Warranties.
So you want a lifetime warranty? What is it exactly? Every manufacturer of a product uses it’s own terminolgy to legally express it’s own terms for their own warranties, always read the terms and considtions carefully. Many manufacturers will stand behind their products and do everything they can to make you happy. A simple definition of a lifetime warranty is a guarantee for the expected lifetime of the product. It does not always imply the lifetime of the consumer, again please read the actual warranty documentation from the manufacturer.

Sometimes products are discontinued or the manufacturer may go out of business, when that happens the warranty may have a limited time period.
