The product quality is very good, the business service is very patient and look forward to the next cooperation

The product quality was opposite of what was shown in the video .once the base was detached from the hinge body I was unable to fix it back .it seems as if it was manufactured by some unprofessional. while shaking hinge it was making sounds parts of hinge were not firmly fixed. insisted them to ship through fedex and beared all the costs of the shipping they agreed to ship through fedex but at last they shipped through china post which delayed my sample by almost 15 days.
