I bought a titanium ring from 60 yuan on Taobao before (I forgot the brand), and the effect was good. After I put it on for ten minutes, my neck seemed to relax. I thought it might be psychological. I asked my mother to try it. She thought it was very useful.
Later, I lost my titanium ring and bought another one, around 30 yuan. The effect is not so good, I have no feeling at all. It seems that we still need to buy the right products.
In addition, titanium ring can reduce the tension, but it is definitely not like TV, just use it. To put it bluntly, it is a temporary solution.
I think even if it is true, the effect is not good.
