The above product models are all products of Shanghai Yongwei Automatic Control Equipment Co., Ltd. In order to confuse the public, other manufacturers deliberately publish the above models on the Internet. It is to enable real users to find the manufacturer's products when they are looking for them. Then they modify the model number and label their own inferior products with that model number, deceiving users and damaging the credibility of the original manufacturer. These manufacturers are generally concentrated in Hunan. Manufacturers in Changsha, Suzhou, Jiangsu, Tianchang, Anhui and other regions.
