Guarantees and Return Policy

  • 14 Days DOA Product Guarantee

    If any item you receive is damaged, defective, or incorrect, it is covered by our guarantee. To initiate a return or replacement, please contact us within 14 days of receiving your order to obtain a Return Material Authorization (RMA).

    For a replacement, we will arrange the return shipment of the defective part. Once the returned item is received and inspected in its original packaging, we will ship the replacement within three business days.

    Note: goods must be returned in their original packaging to be accepted under our Defective on Arrival policy.

  • 30 Days No Reason Return

    Standard in-stock items purchased from JJN may be returned within 30 days of receipt for a refund or account credit, provided the merchandise is unused, resalable, and returned in its original packaging—including all warranty cards, manuals, and accessories.

    JJN will cover return shipping costs in cases of carrier damage, defective items, products that do not match their description, incorrect items received, or unauthorized extra products. For returns for any other reason, the customer is responsible for return shipping fees.

    Please allow 1–2 business days for inspection of the returned product before your refund or credit is processed.

    Note: Products that have been modified are not eligible for return and will void the warranty. Any modified items received will be returned to the customer at their expense.

Limited Warranty:

JJN ("the Warrantor") warrants that its products are free from defects in materials and workmanship under normal use, beginning from the original date of purchase by the customer ("the Purchaser"). This limited warranty applies to significant defects affecting product performance, materials, or craftsmanship.

If a JJN product does not meet the terms of this warranty and the issue is confirmed by the Warrantor’s technical support team, JJN will, at its discretion, repair or replace the defective product with a new or refurbished unit. Replacement products will be compatible with the original item and may, in certain cases, feature an equal or higher power rating.

If repair or replacement is not feasible, JJN may provide a refund instead.

General Conditions for Warranty Claims:

Workmanship and Material Warranty Coverage
If the product exhibits defects in materials or workmanship under normal use (such as failures resulting from manufacturing or material flaws), the Purchaser must contact the Warrantor’s technical support team. A technician will provide instructions for testing or repairing the product. If necessary, the technician may also request that the product be shipped to the support team for further inspection. Warranty service will be provided based on the evaluation outcome.

Eligibility and Claim Requirements
This warranty applies only to the original Purchaser. Customers who received the product as a gift or through resale must contact the original Purchaser to initiate a warranty claim. Valid proof of the original order is required for all claims.

Shipping and Costs
If the original order was shipped within the U.S., any additional shipping costs related to international returns or services are the responsibility of the Purchaser.

Remedies and Limitations
The Warrantor’s sole liability, and the Purchaser’s exclusive remedy, for any breach of this warranty is limited to the repair or replacement of the product (or its components) with a functionally equivalent new or refurbished item, or at the Warrantor’s discretion, a refund of the product’s cost. This warranty does not cover labor charges.

Products that have been serviced or replaced during the warranty period will not receive a new or extended warranty. The repaired or replaced product shall retain the remaining duration of the original warranty period.

No representative, agent, dealer, or other party is authorized to modify or extend this limited warranty beyond the terms expressly stated herein.

Exclusions and Limitations

This warranty does not cover damage or failure resulting from:

  • Normal wear and tear
  • Improper installation, operation, handling, transportation, or storage
  • Inadequate maintenance, ventilation, or cleaning
  • Unauthorized repairs, modifications, or alterations
  • Accidental or intentional misuse, abuse, or neglect
  • Exposure to water (unless specified as waterproof by the Warrantor), hazardous substances, or radiation
  • Electrical issues including power surges, incorrect voltage or current, unstable power supply, system harmonics, or lightning
  • Extreme temperatures or environmental conditions
  • Force majeure events such as fires, floods, earthquakes, severe weather, wars, or acts of terrorism

If the Warrantor determines that the issue is not due to a defect in materials or workmanship, or does not qualify under this warranty, the Purchaser will be responsible for all related costs, including repair, replacement, and transportation.

The Warrantor is not liable for incidental or consequential damages such as installation/removal fees, electrical testing, loss of time, or other indirect expenses.

How to Make a Claim
To assert a warranty claim, the Purchaser must submit a written request to the Warrantor within the warranty period, including a copy of the original invoice and a detailed description of the defect or performance issue.
Returns will not be accepted without prior written authorization.

Eligibility and Claim Requirements
This warranty applies only to the original Purchaser. Customers who received the product as a gift or through resale must contact the original Purchaser to initiate a warranty claim. Valid proof of the original order is required for all claims.

Shipping and Costs

Disclaimer of Liability

Some states do not permit the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you.

Neither JJN, its affiliates, nor its suppliers shall be liable for any damage or loss to items or products connected to or powered by the Product.

In no event shall the total cumulative liability to the Purchaser—under any legal theory or cause of action—exceed the purchase price actually paid by the Purchaser for the Product.

This warranty grants you specific legal rights, which may vary depending on state law. You may also possess other legal rights beyond those described herein.
