“On perusal of your MS. relative to the development of the muscles of the hands, &c., as applied to musicians, I have great pleasure in offering you my testimony to its being a valuable adjunct to musical tuition where mechanical action is required, such as for the piano, or violin and violoncello. I think it shortens the usual routine of practising to gain strength, and will give at once freedom and force to the hand, fingers, arm, &c.”
From J. T. Carrodus, Leader of Her Majesty’s Theatre.

“I am convinced that Mr Jackson’s invention for the development of the muscles of the fingers and hand will be of great value to musical students.”
