I look at the lack of added value of extended warranties by comparing the costs to a lifetime of savings if I never buy extended warranties on ANY product I buy. So far the only time I could have used an extended warranty was for one of our refrigerators where the compressor gave out prematurely. When products gave out, it was always well after an extended warranty would have been expired. I have a 2013 X540 in which I do my own basic maintenance. Keeping the air system clean, oils, etc will go a long way in getting you past an extended warranty period.
