Coverage period
SumoLink provides a 12-month limited warranty from the delivery date for eligible manufacturing defects in the WisdPi WP-UT9 adapter sold through this storefront. Proof of purchase or the SumoLink order number is required.
What is covered
The warranty covers confirmed defects in the adapter electronics, USB-C interface, or RJ45 port that arise during normal use within the coverage period. SumoLink may first request reasonable troubleshooting information to distinguish a hardware defect from host, driver, cable, network, storage, or configuration limits.
What is not covered
The warranty does not cover accidental damage, misuse, liquid exposure, abuse, improper storage, unauthorized repair or modification, altered or removed identifying labels, unsupported third-party driver packages, or damage caused by incompatible or faulty connected equipment. Normal cosmetic wear is not covered.
Compatibility and performance
The warranty does not guarantee that every USB-C, Thunderbolt, or USB4 host will expose a 20Gbps USB path or reach 10GbE-class throughput. Link and file-transfer results depend on the complete host, driver, cable, network, CPU, and storage path. Normal warmth from the aluminum enclosure during sustained traffic is not, by itself, a defect.
Arrival issues
Report visible damage, an incorrect item, or a unit that does not power on or enumerate within 7 calendar days after delivery. Keep the packaging and include photos, video where useful, and the host and cable used for the first test.
Warranty process and remedies
Start through the SumoLink contact page and include the order number, host model, operating system, USB link mode, Ethernet negotiated speed, cable, switch or NAS, driver version, and issue evidence. After confirmation, SumoLink may provide troubleshooting, repair, replacement, or a refund where appropriate and required by law. Do not return hardware until instructions are provided.
Regional consumer rights
This limited warranty is in addition to statutory consumer rights and does not exclude rights that cannot legally be limited.
