Warranty Statement

Our products marked with "20 year guarantee" are manufactured with the greatest care and precision. Products or individual parts with material defects, manufacturing defects or functional errors will be replaced by us within the guarantee period of 20 years from the time of purchase. Should the products in question be removed from the range, Rotho will replace them by supplying similar or equivalent products.

1. The guarantee period applies exclusively to consumer purchases and deliveries and is 20 years. The warranty period begins when the consumer purchases the product. As the manufacturer, Rotho provides the consumer with a guarantee for design, manufacturing, processing and material defects for the products it manufactures during the guarantee period in accordance with the following provisions. Important: This manufacturer's or durability guarantee applies expressly in addition to and dependent on the statutory and/or contractual guarantee of the seller. However, it is excluded if the buyer claims against the seller for the same defect based on statutory or contractual guarantees. The warranty rights of the buyer against the seller are therefore not affected by this guarantee. A reimbursement of the purchase price is only possible with the seller.

2. The durability guarantee only applies to products that are used as intended, properly operated and properly cared for by the buyer.

The durability guarantee does not cover: Damage caused by excessive and improper use and improper use, in particular due to non-observance of the Rotho specifications on the label. The guarantee promise is subject to substantive Swiss law to the exclusion of the United Nations Convention on Contracts for the International Sale of Goods (Vienna Sales Convention).
