As someone who has several ongoing niggling injuries and tightness in tendons and ligaments, I have been wearing this bracelet continuously for 6 months, in particular during workouts and activity and also during rest. I was surprised to find that I had more energy and less post workout soreness whilst wearing the dual loop and I hardly noticed it was there. Whilst no miracle cure (I've still had flare ups of injuries & pain) I do think that it has made a difference, especially to give me a boost to break the pain cycle and keep being active. Due to my experience I am tempted to try a stronger 3-4 magnet bracelet. The only downside with the dual loop is that the fabric strap looks scruffy after long periods of use.
