Hmm. Curiously un-positive responses so far. The warranty being offered cost the end-user nothing.
Obviously, this is not true. You must have no accounting/business background. There is no free lunch in the real world. The warranty does have a cost, and it is passed on to the consumer. All manufacturing costs are passed on to the consumer, and that includes repair costs. So it's like you paid an extra surcharge on the unit's purchase price for insurance purposes. Look at this warranty as a communist proposition. You are paying the costs for repair work being performed on others gear, so that in the event that someday your unit needs serviced, it will be done for no charge.
Maybe the fact that my 18 windows lifetime warranty had no value, since the company that I purchased the windows from went out of business has something to do with my faith in long term warranties. I just had to replace 10 new windows, since 10 of the 18 went bad, and the warranty no longer has any value. FWIW, my 10 new windows also have lifetime warranties. That's the kiss of death for that company. LOL!! ;)
