The product is covered by the warranty if that is stated in the warranty certificate or the invoice. If a warranty is issued for a product, the seller, upon fulfilling the warranty conditions and within the warranty period, guarantees that the product operates faultlessly. When claiming the warranty, the warranty conditions, as stated in the warranty certificate, apply. The seller guarantees the faultless operation of the product for the warranty period, starting from the time the product is delivered to the buyer. The warranty period is one year or as stated in the warranty certificate. The buyer can claim the warranty with the warranty certificate or the invoice, so they should be saved after receiving the item.

If the product for which the warranty is mandatory does not work flawlessly or does not have the characteristics listed in the warranty certificate or advertising message, the buyer may first request the seller to rectify the defects within the warranty period under the Consumer Protection Act. The seller undertakes to eliminate the defects that may occur during the warranty period at their own expense, within a period not exceeding 45 days, starting from the day they receive the returned item. If the product is not repaired within 45 days, the seller must replace the product with an identical faultless product. If the seller does not repair or replace the item within the deadline, the buyer may withdraw from the contract and demand a full refund.

The warranty takes effect on the day the product is delivered to the customer and applies to defects in the material and workmanship and all parts of the product except any consumable items. The warranty is not valid:

  • With failures because of non-compliance with the instructions for use,
  • In the event of failures because of incorrect installation or maintenance,
  • Mechanical damage to the product caused by the customer and failures in the event of force majeure (voltage surge, lightning strike, etc.),
  • If the product has been tampered with by a customer or other unauthorised person (including unauthorised service technicians),
  • When connected to the wrong voltage or type of current,
  • When using other components that do not originally belong to the product.

In the event of a warranty claim, the seller will check whether there is a defect in the material or the manufacturing of the product, and a warranty repair will be performed upon confirmation. If it is found that the damage or defect results from improper use of the product, the claim will be rejected. To enforce the warranty, the buyer can contact the seller or the accredited service centres (listed on the warranty certificate) with the product, the invoice and the warranty certificate.

The consumer’s warranty rights apply without prejudice to the rules on the seller's liability for product defects.

  • if the product is missing an essential characteristic, necessary for its normal use,
