Don't underestimate this product! When you take it out of the packet it looks like another one of those great ideas but you wish you hadn't wasted your money. BUT.... this product is worth every penny and I wouldn't be without it now. Having struggled with a shoulder injury for a while I was damaging my elbow trying to take pressure away from my shoulder. Now every time I play tennis I wear this and what a difference! Even when the injury to my elbow settles I think I will continue with this to avoid any future problems as it gives such excellent support and doesn't cut off your circulation like other products do! Just brilliant.
