Before you make a big buy, you should read the warranty. A warranty is a promise, from the company that made the item or the seller, to stand behind the product. Federal law says that you must be allowed to read the warranty before you buy the item.
Different warranties offer different protection.
It is important to compare warranties before you buy the product. Spoken warranties are promises told to you by a salesperson. It is important to have the salesperson write down any spoken promises. If you do not get it in writing, you may not get the promised service. Implied warranties say that the item will work the way it is supposed to work.
