Wow. I just received this yesterday (last night to be exact) and put it on right away. I felt relief in my upper back/shoulder blades immediately. I personally didn’t think it changed my appearance until I walked by my husband wearing it under my hoodie, and he told me I looked different. “Good different” he clarified.
The instructions say to start wearing it for a short amount of time and work up because it can be uncomfortable. I wore it the night I received it for an hour, and the discomfort I felt was mostly under my armpits, but it wasn’t unbearable and definitely worth that for the immediate change and pain relief.
