Buying insurance (extended warranty or guarantee) on everyday goods / appliances?
IMO it's usually not worth it and here's why. There's a statistical distribution of how likely a unit may fail depending on its age. Probability is high for a short period after the unit comes into use because there are parts that were not thoroughly tested and manufacturing defects. Then all those defective parts fail and get replaces and the unit likely functions without faults for years. Then it reaches it lifetime end and again probability becomes much higher - parts wear out and start failing one by one. Every unit comes with a manufacturer warranty of one to two years already and that warranty will likely cover any defect causes by materials and manufacturing defects - the period when fault probability is initially high. "Extended warranty" only covers the unit for two-to-five years and most units have lifetime of about ten years. This means that the "extended warranty" is in effect when it is least useful.
