I used the product every night, and it worked effectively to help me relieve the pain and swelling in my knees. It is very handy, and I can use it when I am out and at home. When I ordered it online, I thought it may be arriving late. But amazingly, the shipping is extremely fast. I received it earlier than I thought. It also provided amazing after-sales service, and I can know what I am not clear about through its service.
