I used to suffer from cold hands and feet and had trouble sleeping. I consulted many doctors who said I had poor blood circulation and prescribed various herbal medicines, but the results were not significant. Later, I came across this foot spa, which claimed to improve blood circulation through ionic detoxification, so I decided to give it a try. The store owner patiently answered all my questions and recommended the appropriate settings and duration based on my condition. After receiving the product, I made it a habit to soak my feet every night. I set the water temperature to around 42°C, added the Sea Salt packets provided by the store, and soaked for 20 minutes. It felt incredibly warm and comfortable. After 1 wk, I noticed a significant improvement in my cold hands and feet, and my sleep quality improved greatly—I now sleep very soundly! The most surprising part was when I accidentally broke a part of it a few days ago. I contacted customer service, and they sent me a replacement without hesitation. The service is truly exceptional! Now, my whole family has fallen in love with foot soaking, and we all compete to use it every night. It was definitely a great purchase!
