Sujok finger massage rings

I recently came across the finger massage rings recommended by Sujok therapy.These rings look shiny and are  apparently made from a single wire designed to touch most of the acupressure points .They are supposed to be worn like rings and rolled up and down along the finger.The ring should not be worn and only meant for rolling. The massaging is done for all the fingers .2 minutes is the prescribed time for each finger.It is not supposed to be rolled on wounds.Children below 8 years of age should not try this.
The  snug fit ring itself is slightly expandable and dimples the skin on the fingers very superficially for a few seconds.
I am not a Sujok expert but the therapists claim that this practice is said to have very beneficial effects for different kinds of diseases.
