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?

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.

careful when it says high torque. the R390 turn out to have a very slim shaft which is why it does not qualify as a high torque motor. one can grab the shaft and slow it down. therefore it does not function as a high torque device. so if you look at the commonly used 550, 775, 895 etc. their shaft is 3mm or more indication that the motor is very strong and needs a stronger shaft. this motor is for application in areas like little fan or light torque application. Now I need to order a proper high torque motor with at least 3mm diameter shaft. remember that, high torque, bigger shaft.
