Advertising door brand manufacturers prefer Ankuai?

Those who do better will be safe and fast, and will be connected. They are the first to do this, and they have patented technology. Others are mostly imitation small factories. They often shoot several times with one brand 1 year and then shoot several times with another brand. The price is often bottomless and the performance is very unstable. If something goes wrong, the brand is gone, and the promised after-sales can't be guaranteed at all. Before investing, it is recommended to go to the factory for a field trip.
