Please read the following to understand our warranty policy.

Warranty Coverage

Yunyisonic Shenzhen Co., Ltd. (“Yunyisonic”) warrants all products purchased from Yunyisonic to be free from defects in material and workmanship under normal use by the original purchaser for the warranty period specified below.

This warranty ensures that all Yunyisonic products are free from defects caused by faulty manufacturing or defective components, subject to the following terms and conditions:

Except for the warranties explicitly stated herein, Yunyisonic disclaims all other warranties, expressed or implied, including but not limited to implied warranties of merchantability or fitness for a particular purpose.

Any implied warranties imposed by applicable law are limited to the duration of this limited warranty. Under no circumstances shall Yunyisonic be liable for any incidental, special, or consequential damages, including but not limited to loss of business, profits, data, or usage, even if Yunyisonic has been advised of the possibility of such damages.

Repair, replacement, or refund, as applicable under this warranty, constitutes the sole and exclusive remedy for any breach of the Yunyisonic limited warranty. If Yunyisonic is found liable for damages despite these limitations, its liability shall be capped at the most recent distributor’s price of the product.

Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, nor do they allow limitations on the duration of implied warranties. In such cases, these exclusions or limitations may not apply to you.

This warranty provides specific legal rights. Additional rights may vary by state, province, or jurisdiction. You are encouraged to consult applicable local laws.

Warranty Period

During the warranty period, if spare parts are damaged due to manufacturing defects, Yunyisonic will provide replacement parts free of charge, but the shipping cost will be borne by the user.
