Designed to develop & maintain the strength & dexterity of your fingers & hands, the Varigrip's ergonomic design & adjustable tension provides customized conditioning for individual fingers, the entire hand, wrist, & forearm. The reversible molded grip even uncovers simulated strings to help develop and maintain finger calluses when you are away from your instrument.
Adjustable tension - adjust from light to heavy
Molded finger pads for added comfort
Simulated strings for building/maintaining calluses
This is the best finger exerciser I have used. I love the fact that the tent ion is individually adjustable so you can up the tension on stronger finger but leave it lower for weaker ones. Also the built in callus builder is a cool feature although one that I do not use. If you are looking for a new finger exerciser then do not hesitate to give this one a try.
