1 All the products from factory will be tested twice

2 Before our technician makes sure the products are okay to work by two times, we will allow the products to be put in the storage. 

3 Then before we make the package to our customers, our technician will test twice again for the products to make sure they actually work, then we will pack your order to ship to you. 

4 So it will not have any quality problem before you do anything about the product unless there is problem during the shippment.

5 We always welcome your any advice about our products quality control. For any quality control problem, please contact us by: info@bowshine.com. Thanks so much for your long time support and understanding.
