Which is better, Amazon or Senpeptide-based negative ion Kang Jianyi?

For the choice of negative ion health instrument, the most important thing is to look at the negative ion generator inside the instrument and whether the instrument produces ecological negative ions. The negative ion generator filled with ordinary resin used by Amazon is of average quality. It is easy to be damaged by high pressure when used, so it will not produce negative ions. This is because high voltage is needed to generate negative ions. In order to reduce the cost, inferior generators are used and filled with inferior resin. Under the action of high voltage, it is easy to be broken down. Moreover, ordinary carbon fiber is used as the release tip, and the resistance of ordinary carbon fiber material is high. Therefore, when electricity releases negative ions, it will produce ozone, positive ions and other derivatives, which will have a certain impact on people's health for a long time. As follows:

Senpeptide Group adopts a professional negative ion generator filled with high-quality resin or a generator with piezoelectric ceramic negative ion chip technology, which can avoid the problem of breakdown, while the negative ion release tip adopts fullerene, a super-conductive catalyst material, which can avoid the generation of derivatives such as ozone and positive ions, and its service life can be as high as 200,000 hours. At the same time, with the technology of ecological negative ion chip, it can produce ecological small particle size negative ions equivalent to nature, which can easily penetrate the blood-brain barrier of human body. As follows:
