Warranty Period: OpenELAB provides a 12-month warranty from the date of delivery.
Coverage: This warranty covers defects in material and workmanship under normal use.
Resolution: We will repair or replace defective units at no charge.

B. Statutory Rights for EU/UK Customers (EU Compliance)

If you are a consumer residing in the European Union or the UK purchasing from our global site:

Statutory Guarantee: You are entitled to a 24-month statutory guarantee for conformity defects present at the time of delivery, in accordance with EU consumer protection laws.
Relation: The Standard Limited Warranty (Section 1.A) applies in addition to, and does not replace, your statutory rights.

C. Warranty Exclusions (Applies to ALL Regions)

Warranty coverage is VOID if the damage is caused by:

Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.
Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.
Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).
Normal Wear & Tear: Consumable parts (e.g., batteries), unless defective upon arrival.

Note: For non-warranty repairs (e.g., customer-induced damage), we may offer repair services for a fee. Shipping and diagnostic costs will be borne by the customer.

1. Full Refund (100%)

The item is Brand New, Unopened, and Unused.
The original packaging is intact and sealed.
All accessories are present.

2. Partial Refund (Restocking Fee / Value Depreciation)
