Warranty

Last updated: April 15, 2026

All units sold by MBTEK are subject to the warranty terms and conditions set out below.

Claims and Replacement Parts

Each claim for replacement parts must be submitted with proof of the broken or defective element, including videos and pictures.
Claim files may take up to three (3) business days to process. If the product is not in stock, a lead time will be provided.
Shipping fees still apply for replacement parts.
If the product is out of warranty, or if the warranty has been voided, the customer must place an order and pay full price for the required parts.
Duties are not included in shipping charges and may vary depending on the delivery location.

Warranty Coverage

This warranty covers defects in materials, defects in workmanship under normal use, and faulty components under normal use.

For warranty issues, the customer must submit video evidence for review to support@mbtek.com. All claims are reviewed by the MBTEK Tech Support Department, and a response will be issued within ten (10) working days of the original filing.

If a claim is approved, MBTEK may provide replacement parts using new or replacement components. If parts cannot reasonably resolve the issue, the product may be exchanged for a new product. Depending on the nature of the issue and repair required, the product may also be fully or partially refunded.

Standard Warranty Period

The warranty period starts from the delivery confirmation date.

Warranty Extension

Buyer's Obligations

If a product is defective, the customer may be entitled to repair or replacement, subject to warranty review and approval.

The customer must follow all troubleshooting steps provided by MBTEK Tech Support.
If the issue continues, the customer must provide sufficient video evidence showing that the defect is related to manufacturing or faulty parts.
If the customer fails to provide proof and a repair service is arranged on the customer's behalf for diagnosis, an administrative fee equal to 10% of the total repair service cost may be charged. This amount may be refunded if the issue is later confirmed to be covered under warranty.
If a repair service determines that the issue is unrelated to a manufacturing defect or faulty part, the service cost will not be covered by the warranty and will be billed to the customer.
