Yes, Ender 3 Dual Kit is fully tested before shipment. Fujian Huansheng Technology Co., Ltd. is a quality-oriented manufacturer with great achievements in quality control. Before we tapped into the global markets, we paid less attention to the ex-factory inspection, which results in the high rejection rate of the product. Now, since we have conducted detailed quality assurance rules and set up criteria for ex-factory product quality, the pass rate of the product has increased remarkably. Customers can rest assured about the product quality by remotely reviewing our QC process.
