7.1. Claims for material defects by the customer against NIVONA shall become time-barred twelve (12) months from the delivery of the products to the customer. The foregoing provisions shall not apply insofar as the law prescribes longer periods pursuant to §§ 438 BGB (items for buildings), 445b BGB (right of recourse), 327u BGB (right of recourse for digital products), and 634a BGB (construction defects). The statutory provisions on the suspension and recommencement of the limitation period remain unaffected.
7.2. The obligation is to deliver goods of average type and quality, with the standard being the conditions of NIVONA and the average type and quality of its goods. Statements and agreements on quality do not constitute a guarantee unless this is expressly agreed.
7.3. Should the delivered goods or the service be defective, NIVONA shall, without prejudice to any rights of recourse of the customer under §§ 478, 445a, 445b, 445c and 327u BGB, provide a warranty at its discretion through free subsequent performance (rectification or replacement). Further warranty claims for subsequent performance, reduction, withdrawal, or damages are excluded, without prejudice to section 7.5. The right of withdrawal is not excluded if the subsequent performance has failed. The right to damages is not excluded if the subsequent performance was culpably omitted; otherwise, section 8 of these provisions applies to claims for damages.
7.4. No liability is assumed for natural wear and tear or for damage arising after the transfer of risk as a result of incorrect or negligent handling, improper modification or repair work, excessive strain, unsuitable operating materials, or due to special external influences.
7.5. NIVONA shall bear the expenses necessary for the purpose of subsequent performance, in particular transport, travel, labor, and material costs. This does not apply if the costs are disproportionate.
7.6. The delivered goods must be carefully inspected immediately after delivery to the customer or to a third party designated by him. The goods are deemed to have been approved by the customer with regard to obvious defects or other defects that would have been apparent upon immediate, careful inspection, if NIVONA does not receive a notice of defects in text form within fourteen (14) working days after delivery. The customer must report other defects to NIVONA in text form immediately after they become apparent, but no later than within fourteen (14) working days.
7.7. If NIVONA fulfills the consumer's warranty claims directly, the customer's rights of recourse against NIVONA are excluded. Otherwise, the customer's rights of recourse against NIVONA exist only to the extent that the customer has not made any agreements with the consumer that go beyond the statutory claims or made voluntary concessions. The customer's claim under § 445a or § 327u BGB, which must be substantiated, is nevertheless limited to the amount that was necessary for a successful subsequent performance, taking into account economic efficiency. The customer bears the burden of proof for the necessity of higher costs. To substantiate the right of recourse, the customer must enclose a copy of the purchase receipt, a proof of service signed by the consumer with the full designation of the replaced original spare part or a spare part authorized by the manufacturer, and a calculation of the transport, travel, labor, and other material costs incurred. Instead of the above-mentioned individual settlement, NIVONA may, at its discretion, fulfill the customer's statutory right to reimbursement under § 445a BGB by means of a reasonable flat rate, provided this has been agreed. NIVONA reserves the right to set off claims for damages arising from improperly performed subsequent performance by the customer within the scope of its manufacturer's warranty.
7.8. The above provisions apply accordingly to defects of title.
7.9. The provisions of the Product Liability Act (ProdHaftG) remain unaffected by the above provisions.
