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.

Important Notice:

  • Please verify the inventory location on the product page before placing your order to confirm delivery timeframes. 
  • For products in the Shenzhen warehouse, we will typically first ship the products from the Shenzhen warehouse to our Munich warehouse or Long Beach warehouse, which will take around 1.5 weeks. After we receive the shipment in Munich/ Long Beach, we will send the items to you. We will only arrange YunExpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50.
  • If you place an order with products from both Munich and Shenzhen warehouses, we will first ship the products in the Munich warehouse, and then send the remaining products to you when we receive them from Shenzhen.

 

3. International Warehouse

Our products are stored in both our Munich 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.

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

We will only arrange YunExpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50.

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.
