5-year Berger guarantee:

The guarantee period is five years and begins on the date of purchase or the day the goods are handed over. A copy of the proof of purchase is required to assert warranty claims. The repair service will decide at its own discretion whether a repair or exchange is necessary. The warranty does not cover damage caused by

• Accidents,
• unforeseen events (e.g. lightning, water, fire, etc.),
• improper use, transportation or improper use,
• improper cleaning,
• other improper processing or modifications to the product

Traces of use that occur during normal use (e.g. scratches, dents, etc.) do not constitute a warranty claim.
