There is no limit to the number of repairs, but if the product is completely replaced (the entire warranty period has expired), the warranty will terminate with the supply of a replacement product.
Maximum warranty period is 10 years (including 1 year manufacturer's warranty). The insurance premium can be set at 5-10% of the selling price depending on the guarantee conditions. By using a reasonable contract method, assuming the maximum amount of compensation for each department (unit), proposals can be made that have little impact on business investment activities.
