Well, as/for a guitarist, it's a must-have item. After playing the guitar, take a break with this tech to relax and de-stress the fingers. it's a great work out.
Also, it's equally useful and applicable to sportsman, pianist or activities that involve stress over fingers and of very reasonable price.
Loved it and highly recommend it.
