Here's how to proceed in each case:

1. Product damaged during shipping

When you receive the product, you should check it well. If you find that it has been damaged during shipment, you must inform the courier as soon as you receive it and return it at the same time. If you detect damage after delivery, request a return through the "My Order History & Details" section.

2. Wrong product

3. Defective Product

For the return due to defective product, it will first be necessary to verify the defect of the part by sending photos in which it is verified that the element is really damaged or deteriorated. From here on, everything is up to us. Request the return through the "My Order History & Details" section.

4. Product Doesn't Meet Your Expectations

If you receive the product and it doesn't respond to what you were looking for, don't worry, you can return it within 14 calendar days of receiving it. To do this, simply contact Master-Ecu through the "My Order History and Details" section. It is necessary that the product is in perfect condition with all its packaging and accessories.

Do not forget to keep the original packaging, because if you do not return the product in the original packaging, the product will suffer depreciation. We recommend that, in case of returning the product already opened, you re-pack it very well with all the protections with which we supply it from Master-Ecu and avoid damaging the original packaging of the product with packing tape etc...; Keep in mind that it can later suffer blows in transport and if we receive it badly damaged we will have to apply an extra cost for this depreciation of the product.
