All goods can be returned FREE of charge within 30 days after purchase without giving reason. This means that we pick up the goods that you want to return at your place for free and return the money to your account within 3 days after returning the goods. You only need to write an email to firstname.lastname@example.org or call +420 777 670 947. The goods must be properly packed to avoid any damage during transportation and must be in the same condition as they were during packaging at our warehouse. We are not a rental. The guarantee is there for trying the equipment, not for its repeated use.
