I bought this last year, thinking it might suit my son who has a habit of twisting his hair while studying, but it didn't seem to work for him, so he hasn't used it. The following is an excerpt from the Amazon purchase site: This massage ring reduces anxiety, relieves stress, and promotes blood circulation in the fingers to some extent. The spiky therapy ring can be used while working on a computer or after driving. Enjoy a sensory experience outdoors with the compact sensor ring. It's small enough to fit in a pocket or backpack, so you can enjoy a pleasant stimulation wherever you are. This massage ring reduces anxiety, relieves stress, and promotes blood circulation in the fingers to some extent. It's perfect for students, office workers, etc.
