Review on Vive Arm Sling Immobilizer Subluxation by Mack Douglas

I liked the idea of this sling. The one I got from the doctor is awful - uncomfortable and no breathing. My arm is broken, I can't move much. I can't get into this strap on my own - the velcro that comes loose doesn't slide back through the pull tab easily - the two-handed man struggled to get it in there and the front strap isn't long enough for me to fasten it solve. Hooks over my head without moving my arm/shoulder. It also doesn't come off easily (which would be nice if there was a different sling entrance).
