3. Warehouse Locations

Our products are stored in both our U.S. and Global warehouses to provide more flexible logistics solutions. On each product's description page, we indicate the specific warehouse location.

3.1 U.S. Warehouse

At OpenELAB, we are committed to providing accurate product descriptions and high-quality electronics. The following policy outlines your rights and obligations, designed to be fair to both our customers and our business operations globally.

1. Warranty Policy

A. Standard Limited Warranty (Global & US)

For customers in the United States, Asia, and other non-EU regions:

  • 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.

  • 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:

  1. Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.

  2. Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.

  3. Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).

  4. 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.

2. Return & Refund Policy

A. Return Window

  • Standard: You may request a return within 31 days of receiving your order.

  • EU Customers: You have the statutory right to withdraw from the contract within 14 days of receipt without giving a reason.
