If you need to return an item, contact SumoLink support before sending it back. Include your order number, reason for return, and whether the product has been opened or used.

Returned items should be complete and protected for shipping. Refund approval, restocking conditions, return shipping responsibility, and processing time must match the final policy configured in Shopify Admin.

Compatibility-related returns should include the host model, OS version, USB link mode, and network equipment used so support can verify whether the issue is product, driver, or setup related.
