Special warranty considerations

Macu warrants all of its Products for a period of two years, (i) to be free from defects in design geometry, materials and workmanship and (ii) to comply with the specifications provided to and accepted by Macu, taking into account the limitations standard and limitations of current 3-D printing technologies provided to their normal wear and tear and (iii) their intended use following all of Macu’s instructions and requirements (the “General Warranty“).

Irrespective of the foregoing, the General Warranty does not cover defects and damages due to (i) on-site printed customized designs (i.e. Macu explorer), (ii) accidents, neglect, misuse or operation beyond Macu’s capacity, (iii) parts damaged by improper modification, installation, false specification or measurement, substitution of parts, not approved by Macu, (iv) any alteration or repair by others that, in Macu’s judgment, materially or adversely affects the product, part or service, (v) that were not possible for Macu to know, given the state of scientific and technological knowledge at the moment the product was put into circulation; (vi) and/or to the conformity of the Products with binding government rules. Furthermore, the General Warranty does not include insignificant deviation of the quality of the delivered Products. It is thereby acknowledged that the color of the Product may vary and abrade due to normal wear and tear.

It is the sole responsibility of the Customer to provide the correct measurements required for the configuration of any Products of Macu, unless measurements are taken by or directly assisted by Macu. Macu explicitly disclaims any liability and warranty for the correct measurement, provision of the spacer lengths and any new or final products assembled with Macu’s Products, unless measured in conformance with all Macu recommendations or directly by Macu.

The General Warranty only applies to the Products, subject to normal usage of the Online Configurator, without unapproved arm measurement methods and arm stump characteristics not supported by the used system or Macu. Macu provides the use of the Online Configurator on an “as is” basis and does not warrant for the merchantability of any software application required for the use of the Online Configurator.

For the avoidance of doubt, there is no defect if an individual adaptation of the delivered Product is no longer possible due to unforeseeable physical changes in the wearer of the Product between the time of the Order and the adaptation date.

Macu is not responsible for the durability and useful life of the Product or any final product the Product is used for, if materials are added to the Product or the Product or a final product the Product is used for is assembled by any third party, including the Customer (e.g. an Atop or BOA lacing system added by a Customer). In particular, any warranty and liability due to the assembly of the Product or the assembly of a final product the Product is used for by a third party, including the Customer, is excluded.

We shall in any case be liable without limitation for claims due to damages that have been caused by us, our legal representatives or legal agents
• for injury to life, limb or health
• for deliberate or grossly negligent breach of duty
• for guarantee commitments, where agreed
• towards consumer.
