Hello, if I extend the warranty to 5 years for an additional CHF 15.20 when I buy a hand blender and the manufacturer's warranty is already 2 years, what is it exactly? do I have a total of 7 years warranty on the appliance or only a total of 5 years? Or to put it another way, is the warranty extension actually the warranty period (in years) that I buy in addition or is it then the total warranty period including the manufacturer's warranty? Does this mean I have bought a warranty period of an additional 5 years or only 3 years? Thank you very much for the answer and kind regards
