Find out whether the product comes with a full or limited warranty. Note that the manufacturer's warranty is often limited to manufacturing defects, doesn't protect your item from normal wear and tear, and may not cover cosmetic damages. Find out whether the warranty covers both parts and labor.
Labor can end up costing as much as or even more than parts.
Check to see whether there is a replacement clause. With this coverage, you will receive a brand-new product if the original cannot be repaired. Find out whether a loaner is included. With automobiles and appliances in particular, see whether the warranty gives you a loaner while your product is being repaired. Check to see how long the warranty will be in effect.
