How do you ship packages?

Do you ship worldwide?
Yes. We provide free shipping to over 200 countries around the world. However, there are some locations we are unable to ship to. If you happen to be located in one of those countries we will contact you.
What about customs?
We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Do you provide tracking information?
Yes, you will receive an email once your order ships that contains your tracking information. If you haven’t received tracking info within 5 days, please contact us.
My tracking says "no information available at the moment".
For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.
Will my items be sent in one package?
For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you have specified combined shipping.
If you have any other questions, please contact us and we will do our best to help you out.

The product is excellent. The points in favor of this article are as follows: -Delivery was one week before the proposal by Ali express. -The product comes complete and well assembled. -During the tests it was provided with 5v, and 9v accompanied by an Arduino for the control of the engines and the results were execlent since it fulfilled its function and was able to move 3 engines without burning for approximately 1 hour of continuous use, in addition to other tests done on 5-minute properties. Negative points I do not have given that the item meets what the seller states in addition that the results showed that the engine controller is of very good quality. In summary this product meets what the seller promises and is of a very good quality.
