There are too many Shannics on the market, and they all have different prefixes. You need to look for the trademark. The earliest Shannics in China is actually the current Shenchi. The trademark used to be a circle with a circle inside it. Huo Miao and SNS. Nowadays, Huo Miao is no longer used. SNS is basically used. There are many counterfeit products on the market. When purchasing, you must be careful about the trademark and anti-counterfeiting. SNS now has its own anti-counterfeiting code. Airtac is from Taiwan, but it is mainly sold in China. In terms of production, in terms of current output value, AirTAC is of course larger, because the price is nearly twice as high as Shenchi. But which one has better quality depends on the specific product. The overall quality stability of the product may be inferior to that of Shenchi. Deke is better, but the after-sales service may be better than Shenchi, because Yadeq doesn’t seem to have a three-guarantee policy, but Shenchi does, and Shenchi’s connectors are nationally famous, and Shenchi is more willing to provide customers with customized services. , for many manufacturers who want to reduce the cost of accessories without affecting quality, then Shenchi should be a good choice!
