Once your order is placed and paid for  we will build your unit and ship it to you in a timely manner. Every order is a custom build and there are no returns accepted unless of a defect or damage during shipping. In the case of a defect, we will replace the unit or fix the unit returned. We are not responsible if you break the unit by not following the instructions. If the unit is shipped out of the United States, we can not be responsible how your country handles customs, tariffs or additional charges.  If the unit comes back to us, then you are responsible to pay for the shipping for us to resend it.
