What is their warranty like?
I read 12 months here and there on different message boards and vendors' websites, but this is all I found in their manual:
17 Guarantee conditions, handling a guaranteeConditions:
• Statutory guarantee conditions apply. The guarantee period for users is reduced to the
regulations applicable to commercial customers to the extent that they are making use
of a device suitable for commercial use, including in part.
• Transmission of a copy of proof of purchase is a prerequisite for guarantee claims
against us or one of our dealers. For verification of the guarantee refer to the note on
handling a guarantee below.
• For quick processing of guarantee claims, please inform us immediately in writing
upon noticing defects, and include a fault description and photos where applicable.
• No guarantee is given for defects due to non-adherence to the operating instructions,
improper treatment or normal wear and tear of the device. Guarantee claims are also
excluded in terms of brittle components or expendables such as seals or similar.
Finally, guarantee claims are excluded where work is performed on the device by nonauthorised
parties.
