Hello! As a famous brand product and famous trademark, Guangdong Suixing Cable should have complete certificates and certificates, including whether there is a quality system certification; whether the certificate is standardized; whether it has the factory name, factory address, inspection seal, and production date; and whether it is printed on the wires. Trademark, specifications, voltage, etc. Also look at the cross-section of the copper core of the wire. The copper of Suixing cable is bright and soft in color, otherwise it is a fake product.

You can take a wire end and bend it repeatedly by hand. The wires and cables produced by Guangdong Suixing Cable are soft to the touch, have good fatigue resistance, have high elasticity in the plastic or rubber feel, and have no cracks in the wire insulator. Hope this helps you
