Well I can't say about other users what they think and how much protected byvCTK Braces but in my case first few weeks it was not so effected but later tremendously improved relief in my both knees.
One very important question is - this is not a fashionable product . This is very useful for joint protection for those people who are facing hard pressure every day due to their activities like sports person, cyclists and hard movements schedule, CTK providing different type of braces for different purpose..If user couldn't decide own ,they should speak to their customer services for right brace selection for best results instead blaming company.
