"Skill in playing musical instruments is acquiredonly after prolonged practice which endows the performer's fingers with nimbleness, independent action and strength.

“I am using the Ochydactyl every morningfor approximately 7 minutes per hand. It eliminates the tense exercises of pure velocity. It is particularly useful for the preparation of my concerts.”

"In 5 minutes it provides the same agility as an hour and a half of study."
