1.1 Standard Coverage

• Free Warranty Period: 1 full year from the date the product is delivered and accepted (or 30 days after delivery if acceptance testing is not completed—deemed accepted by default).
• Lifetime Service Guarantee: After the warranty expires, we offer lifetime paid repair service—you only pay for actual parts cost + reasonable labor. No base maintenance fees ever.

1.2 VIP / Long-Term Customer Policy

For established repeat customers and authorized distributors, we may extend free repairs or replacements beyond standard warranty terms (based on purchase history or agreement). For out-of-warranty repairs, round-trip shipping is borne by the customer.

1.3 Warranty Extension Rule

If a repair or replacement is required due to a quality defect, the warranty on the repaired/replaced part or unit restarts from the date it is redelivered to you. The extension covers both repair time and shipping duration.
