There were time-consuming difficulties, but with dedicated perseverance on behalf of the manager(?) I am now in possession of this very efficient massager.
Purchased to work on long term trigger finger and recent shoulder impingement. Already see improvements and very pleased with this massage ball. It's quite big but you can still accurately pin point precisely. I have a branded vibration roller but made no difference to my injuries. Not expecting the ball to be the cure but certainly contributing.
