Refund policy

At Zeroline, every gauge is individually assembled, tested, and quality-checked before it leaves our workshop.

If your product arrives faulty or experiences a genuine manufacturing defect, we'll work with you to diagnose the issue remotely. Many issues can be resolved through software updates or troubleshooting without requiring the unit to be returned.

If the issue cannot be resolved remotely, we may request that the product be returned to us for inspection.

Eligibility

To be eligible for a refund or replacement:

• The product must have been purchased directly from Zeroline.
• The issue must be due to a manufacturing defect or fault.
• The product must not have been damaged through incorrect installation, misuse, modification, or accidental damage.

Return Shipping

Customers are responsible for return shipping costs unless otherwise agreed by Zeroline.

We recommend using a tracked shipping service, as we cannot accept responsibility for items lost during return transit.

Inspection & Resolution

Once your returned product has been inspected, we will:

• Repair the product where possible;
• Replace the product with an equivalent unit; or
• Issue a full refund if a manufacturing fault is confirmed and repair or replacement is not appropriate.

Refunds are processed back to the original payment method.

Change of Mind

Due to the nature of our products and our small-batch manufacturing process, we do not accept returns for change of mind once an order has been shipped.

If you have any questions before purchasing, please contact us and we'll be happy to help.
