Warranty exclusions
The warranty is limited to technical defects and component issues that affect the functionality of your item. The warranty will not cover your item if it is:
Lost, dropped, or broken
Damaged by liquids (oxidation)
Opened for repair or diagnosis by a third party (other than the seller)
In other words, if a malfunction occurs with your item, but it has been broken/oxidized/opened by a third party, or shows signs of impact due to a fall, the warranty will no longer apply.
