In the event of a warranty claim, the manufacturer exchanges the product concerned for a new product or reimburses the customer for the purchase price. The manufacturer has a choice between replacing the product and refunding the purchase price. If the manufacturer chooses to replace the product, the old product is replaced by a new product of the same kind, same quality and same type. If the product type in question is no longer manufactured at the time the fault is reported, the manufacturer is entitled to supply a comparable product. The transport, travel, labour and material costs necessary for the replacement shall be borne by the manufacturer. If the manufacturer chooses to reimburse the purchase price, he shall confirm this in writing to the customer. The purchase price is refunded step by step against return of the product concerned to the manufacturer. On the basis of the warranted deceleration, no further services of the manufacturer are provided to the customer (e.g. the payment of damages).
