I bought this magnet collar, too. At first, I heard it was very charming, so I bought it. Actually, I don't feel anything when I wear it. Like many exposed health care products, many people said it was effective at first. I don't know, it should be psychological. After all, they spent hundreds of dollars on it, hoping to have some effect.
Some friends upstairs are very reasonable. CCTV exposed all kinds of so-called magnetic therapy collars and bracelets. These things are deceptive in themselves. These diseases are accumulated for a long time, and there will be no specific medicine to make them recover. If you really want to buy it, buy it. I don't think it's necessary.
