Return Shipping Cost

WattCycle Pays For Return Shipping

WattCycle will pay for the cost of return shipping if the reason for the return was the result of our error.

Examples of instances may include:

Item arrived defective and cannot be fixed with a replacement part.

We shipped out the wrong item.

We shipped it to the wrong address.

We shipped a duplicate order.

Item malfunctioned during the 30 day returns period. (The customer should install and operate the item properly per the product manual instruction.)

Attention

For items that arrive damaged or are defective, the customer MUST provide videos or photos to support the claim that the item arrived damaged or is malfunctioning. If a customer refuses to or fails to provide videos or photos of a claimed malfunctioning/damaged item, this return will be treated as “buyer’s remorse” and the customer is solely responsible for shipping it back. Once we have received the approved returned item, we will review its condition. If the item is found to be defective, we will issue a refund within 3 working days.

Customer Pays For Return Shipping

In the case of a return due to customer error, return shipping is the customer’s responsibility and shipping charges are paid by the customer. Fees vary by country, please contact us for specific fees.

Return Item & Address

After confirming with our customer service team that a return is possible, we will provide you with a return solution based on your order's fulfillment warehouse.

If your order was shipped from a German warehouse, we are unable to provide a return label. You will need to contact our customer service team to obtain the return address and arrange the return yourself.

If your order was originally shipped from a Polish warehouse, we will provide you with a return label. You simply need to take the product with the return label attached to a courier station to ship it back.

Refund

For non-quality-related issues and unopened packages, you will be responsible for covering the round-trip costs (including shipping fees and handling charges). Costs vary by country/region.

For quality-related issues reported more than 30 days after the purchase date, WattCycle will provide a partial refund based on the product's usage condition.
