All manufacturers know what it costs, on average, to provide warranty services. They are not stupid. The reason they sell extended warranties is that they can make PROFIT by selling you another product (extended warranty) on top of the product itself. So, if they know what it costs, and they make a profit on it, that means you, the consumer, are paying what it costs, on average, to repair your machine, PLUS a little extra profit to the manufacturer. It's that simple. That being said, there are two reasons you might want to purchase it, even though the law of averages says you shouldn't. The first reason is that you fear you may not have the money when the equipment breaks to pay for the repair. In other words, it's an insurance policy. Better to set some money aside in a repair fund. Second, you know yourself and you relaize you are terrible on routine maintenance or you are prone to damaging equipment at a higher rate than most users. In either case you deserve to pay more , and you should learn that good maintenance and taking care of your equipment can save you money by reducing costs like uneccesary extended warranties. Plus, warranties don't usually cover the type of damage you can self-inflict on your machines. Most real manufacturing problems show up early on, especially if you use the equipment regularly. And if you don't, why buy more warranty?
