We provide a 1 year warranty against manufacturing defects (unless otherwise stated). The warranty does not include wear or user damage. Without proof of purchase, we do not accept warranty claims. We provide quality products and we rarely have any warranty cases. However, If any parts need to be changed within the 1 year duration, we ship the parts directly to our customers at no charge and we assume responsibility to our customers for exchanging the actual parts in the instruments. These parts will be shipped from Asia by air in most cases. We apologize for any inconvenience that you may occur during this process and we would like to ensure you that we will do everything we can within reason to ensure great performing products. Please contact Abyvo customer service at email@example.com for assistance.
