Okay in a pinch, but far from perfect
Pro's: it's better than nothing, and for the price, no complaints<br />Con's: sizing and design fails.<br />Notes: I am 5'3&#34; medium build.  I ordered Small and Medium, having read elsewhere that sizing ran small.<br />The shoulder section for the Small size isn't bad, but it despite the multiple attachment points it's difficult to get good compression without fabric rumpling in uncomfortable ways. And the arm section was so beyond ridiculously small it wouldn't pull up over my tiny bicep. At. All.<br />I'm an experienced gadgeteer, so judicious use of scissors plus addition of a stray velcro snap on the arm and padding under the shoulder top fixed it up perfect for me, and once fitted, it does stabilize the joint without impeding range of motion. So, it works. Sort of.<br /><br />The Medium, in contrast,  is much too big through the shoulder and back to get any kind of decent fit.
