For me this has been absolutely amazing for my shoulders. I happen to be right in the middle of the L size so when I put it on it's tight enough that I feel it in a good way, but it's not so tight that it hurts or cuts off circulation. I was having a lot of pain in my shoulders from almost every exercise and after wearing this for about a week, maybe a couple hours a day, it vanished completely. Like gone. I can't imagine it works like this for most people but for me this has been basically a minor miracle. I still put it on for a while sitting at my desk each day and I have been doing dips, rows, overhead presses, all totally pain free for the first time in months. Couldn't have asked for better results personally.
Also- I attached a daisy chain to the loop in the back so I could reach behind and pull it down. Feels better if it's adjusted periodically.
