I only make a few models with excellent quality, some are expensive and some are relatively economical. The low price of the economic version 06 police model does not mean that the product quality is not good. I just want to earn some popularity and lay the foundation for long-term cooperation. All quality and reputation are the most important. You will know what throwing a stick is by comparing the genuine product with the defective product. My QQ nickname is self-defense product or Taobao Want Want Happy Jupiter.
