Landlord, I used it. That's totally useless. I followed the trend and bought it online with my classmates. Wearing it on my big toe for a few days made me feel uncomfortable, and then I took it off and put it in the corner. It's no use wrapping my feet like gauze and making them feel very hot. The best way is to eat less meat or something, try not to eat at night, just eat a la carte or fruit ~ get up in the morning and drink honey water on an empty stomach, that's it, haha ~
