Guarantee & Return Policy

Effective Date: December 10, 2025

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.

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:

  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.

B. Refund Conditions & Restocking Fees

To protect against policy abuse, the refund amount is strictly determined by the condition of the returned item.

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)
If the item is returned in a condition that prevents it from being sold as new, OpenELAB reserves the right to deduct a Restocking Fee (for US/Global) or Compensation for Loss of Value (for EU) from the refund amount.
Deductions apply if:

  • Signs of Use: Visible scratches, mounting marks on screw holes, or fingerprints.

  • Damaged Packaging: Original box is torn, written on, or missing.

  • Technical Modification: The device has been soldered, permanently installed, or flashed with unauthorized firmware.

  • Broken Seals: Anti-static bags or security seals have been opened.

Depending on the severity of the usage/damage, the deduction may range from 15% to 50% of the product price. Items damaged beyond repair due to misuse will not be refunded.

C. Shipping Costs

  • Defective / Wrong Item: OpenELAB covers the return shipping cost.

  • Customer Remorse (Changed Mind / Ordered Wrong Item): The customer is responsible for all return shipping costs to our designated return center (located in the US, Germany, or China, depending on your region). Original shipping fees are non-refundable unless required by local law.

3. Return Process (RMA)

To ensure a smooth return process, please follow these steps:

  1. Authorization: Contact us at info@openelab.io before returning any item. Returns without prior authorization will not be accepted.

  2. RMA Number: We will provide you with a Return Merchandise Authorization (RMA) number and the correct return address.

  3. Packing: Ship the item back in its original packaging with the RMA number clearly marked on the shipping label (not on the product box).

  4. Tracking: We strongly recommend using a trackable shipping method. OpenELAB is not responsible for returns lost in transit.

M5Stack StackChan Open‑Source AI Desktop Robot (Available for delivery from April to May)

119,00 €

StackChan is an adorable open-source AI desktop robot co-developed by M5Stack and its global user community. At its core is the M5Stack flagship IoT development kit CoreS3, powered by an ESP32-S3 SoC with a 240 MHz dual-core processor, 16MB Flash, and 8MB PSRAM, supporting both Wi-Fi and Bluetooth LE. The main unit features a 2.0-inch capacitive touch display with a durable glass cover, a 0.3 MP camera, proximity sensor, 9-axis IMU (accelerometer, gyroscope, magnetometer), microSD card slot, 1W speaker, dual microphones, and power/reset buttons.

The robot body connects to the main unit and includes a USB-C port for power and data, a 700 mAh battery, and two feedback servos—one for 360° horizontal rotation, the other for 90° vertical movement. It also integrates 12 RGB LEDs, an infrared transmitter and receiver, a three-zone touch panel, and a full-featured NFC module.

The pre-installed firmware offers a rich set of features, including expressive animations, the XiaoZhi AI assistant, and support for iOS video calls, remote avatars, and device discovery among nearby StackChan units. It’s fully programmable via Arduino and UiFlow2, making it easy to customize behaviors and expand functionality.

Note: The product packaging and software development are still in progress. Final features and documentation may change. Thank you for your understanding.

Important Notice:

  • Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Long Beach warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
  • Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Long Beach warehouse first (typically taking 5-10 business days) before dispatching them to you.
  • Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.

3. International Warehouse

Our products are stored in our Munich, Long Beach, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.

3.1 German Warehouse

For products stored in our warehouse in Munich, we use either Deutsche Post or DHL for shipping, depending on the size of the package. Logistics within Germany are very efficient, with an estimated delivery time of 2-4 business days, ensuring you receive your order quickly and conveniently. For Western EU countries, the estimated delivery time is 4-6 business days. For Eastern EU countries, the estimated delivery time is 6-8 business days.

3.2 US Warehouse

For products stored in our warehouse in Long Beach, we use either USPS or UPS for shipping, depending on the size of the package. Logistics within U.S. are very efficient, with an estimated delivery time of 3-7 business days, ensuring you receive your order quickly and conveniently.

3.3 Chinese Warehouse

For Pre-order items or orders fulfilled directly from our Shenzhen warehouse, we utilize YunExpress for reliable international shipping. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors. Otherwise, products will be restocked to our Munich or US warehouses before final delivery, as detailed in the "Important Notice" above.

4. Customs and Taxes

4.1 How are customs handled by OpenELAB for import or export?

For EU Member States: Whether shipped from Germany or China, we cover all import duties and taxes (DDP), ensuring that you receive your package without any additional costs or hassle with customs.

Important Exception for Non-EU Countries (e.g., Switzerland, Norway):
For countries outside of the European Union, such as Switzerland and Norway, you may be subject to import duties, taxes, and/or customs fees charged upon delivery. These fees vary from country to country and are the sole responsibility of the recipient.

⚠️ Refusal of Delivery: If you refuse to pay these fees upon delivery and the package is returned to us, the refund amount will be calculated after deducting the original shipping costs, return shipping costs, and any applicable customs or storage fees.

4.2 How is VAT charged when the Customer places an order from OpenELAB?

In accordance with the newest VAT e-commerce rules in the EU, OpenELAB shall have the right to charge the amount of VAT at checkout. The standard rate of actual VAT applied is subject to the destination country's regulations. No additional VAT will be charged upon delivery for these orders.
