The legal warranty ( warranty for defects) is valid for 24 months from the date of purchase and is an obligation for the dealer (seller). This must guarantee that the sold goods are free of defects. If this is not the case, the customer has the right to repair or free replacement. The defective goods must be sent in for this purpose. If neither repair nor replacement is possible, the customer can demand his money back or a reduction in the purchase price. If the defect occurs within the first 12 months, it is assumed that the defect was already defective at the time of delivery to the customer. After 12 months, the customer must prove this (reversal of the burden of proof).
