Thank you for choosing my services. I offer a one-week warranty on all repairs. After the repair is completed, I kindly ask that you test the device thoroughly before leaving or as soon as you return home. If a fault arises within one week that is directly related to the repair, I will address it at no additional charge. Please note, however, that any damage due to accidental misuse or external factors after the repair will not be covered. Thank you for your understanding.
