Query: Not so good for dislocated shoulder

This immobilizer works fine once you get it on, but it is bulky, difficult to adjust, and difficult to put on out of the box. The elastic type of immobilizer is better because you can usually get it on yourself and its ten times more comfortable. Presumably, you are looking at this as an upgrade from the one they gave you at the hospital and I am telling you this is a purchase you will most likely regret. It has the proper design elements to immobilize your shoulder better than a standard arm sling, but those elements are so poorly put together that you are better off without it.
