If you find any defected pieces from the shipment, please contact us wthin 7 working days and show us some pictures or videos. We will ship you new ones in your next shipment or deduct the amount from your next order or return you those amount back by western union or paypal.
During the guarantee period, we supply parts to repair or resend new ones to cover your lost.

That is fair for both of us.
