Pneumatic brand: which quality is better?

There are too many markets in Shannai, and the prefixes are actually different. Looking for a trademark. The earliest kaempferia in China is actually the present wonder. Trademark used to be a circle with flame and SNS. Now you don't need flame, you basically use SNS, and many people pretend to be the market. Look for the trademark and anti-counterfeiting when you buy it. SNS now has its own security code. Yadeke comes from Taiwan Province Province, but it is mainly produced in China. At present, of course, Yadeke is relatively large, because the price is nearly twice as high as Shenchi, but whose quality you say is good depends on the specific products. The overall quality stability of products may be better, but the after-sales service may be better, because Yadeke seems to have no three-guarantee policy, but Shenchi does, and Shenchi's connectors are well-known throughout the country, and Shenchi is more willing to provide customized services to customers, which makes many factories want to reduce accessories without affecting quality.
