A full warranty is a type of guarantee that promises to repair or replace a product if it has defects in materials or workmanship. This warranty typically covers the entire cost of repairs or replacements for a specified period, ensuring that the consumer does not incur additional expenses for these issues. Full warranties often come with specific terms and conditions, such as requiring the product to be returned to the manufacturer or an authorized service center. It's important for consumers to read the warranty details carefully to understand what is covered and any limitations that may apply.
